Magnus
A downloadable game for Windows and macOS
Magnus is a tactical, chess-inspired roguelike.
Place your pieces one by one to destroy volatile forms. Leave any forms in play and they’ll explode at the end of the round, damaging the board. Expand your arsenal with new pieces and upgrades, then brace for the next wave as the threat escalates. Fail to protect the board from total collapse, and it’s game over.

Tactical, Chess-Inspired Gameplay
Place your pieces on the board and eliminate crystal-like forms using chess-based threat patterns and thoughtful positioning. Survive each round by any means necessary.
Upgrade and Adapt
Modify pieces at the end of each round with powerful upgrades, or expand your arsenal by adding new pieces to your lineup. Alter how your pieces target forms, interact with the board, and synergize with one another. No two games unfold the same way.

A glimpse at some of the upgrades you’ll use to transform your ordinary chess pieces into super chess pieces.
Layered Strategic Decisions
Every turn is a puzzle: which pieces to deploy, which forms to strike, and when to yield or execute. The right upgrade at the right moment can create devastating chain reactions from a single placement.
Persistent Pressure
Surviving a round isn't enough. Forms grow in strength and number with each round. Fail to eliminate them all, and they’ll destroy tiles and erode the board's integrity. Let board integrity fall to zero, and the game ends.

Magnus is still in its early stages. What you’re playing here is a prototype built over just two months to explore the game’s potential and share its core ideas with players. My goal is to see how Magnus resonates with you and use that feedback to help shape its future.
I’m a solo developer working on Magnus in my spare time. The dream is that the success of a game like this could allow me to make games full-time, and maybe even grow the team beyond… well, just me.
You might run into the occasional oddity or bug, but I’ve packed as much as I could into this build to give you a taste of what Magnus can be. And this is just the beginning - think way more upgrades, new mechanics, and entirely different ways to play.
If you enjoy your time with Magnus, your feedback, support, and even just sharing it with others would mean the world and help bring the full vision closer to reality.

It doesn’t end here. Stay in touch and help shape Magnus’ next moves:

Magnus is a delightful blend of chess strategy and roguelike excitement! I was thrilled to see them explore game development, and the result in a demo that's both challenging and addictive. The chess-inspired gameplay is cleverly adapted to fit the roguelike format, offering a fresh take on a classic game while also showcasing visible inspirations such as Balatro. I loved the depth of strategy and the unpredictability of each run. Well done, and I'm looking forward to seeing how the rest of Magnus unfolds!
I’ve tested this game at multiple stages of development, and I want to start by saying how much I appreciate this latest update. The piece projection, advanced tutorial, and being able to read my upgrades mid-epoch are all fantastic quality-of-life improvements, especially for players like me who are still finding our feet.
Beyond the core mechanics, what I really enjoy is the attention to detail. Everything feels intentional and well thought out, and I love that. The aesthetics are spot-on, and even small touches like the sounds in the shop are incredibly satisfying.
There are a few areas where I think the experience could be pushed even further. For example, the destruction phase feels a little too quick. I often don’t have time to really absorb the impact of my board losing integrity because it all happens so fast. It might feel more impactful if the forms shook or quaked before exploding, to build tension, and if the integrity bar came front and centre as it decreased before returning to its place. That extra emphasis would make the consequences of missing forms feel more meaningful.
I also feel there’s a slight imbalance between the “life” of the pieces and the forms. Pieces are loaded with information, while forms are left mostly to interpretation. It might help to add some visual indicators to the forms for example, showing when they’re pinned or when buffs and debuffs apply. That would bring more clarity and balance between the two sides.
Lastly, I noticed that the end-of-epoch summary shows my fragments but doesn’t list upgrades like Finishers Fee. Since these directly affect fragments, I was hoping they’d be included. Having a “summary” without all the key influences feels a bit incomplete.
That said, these are relatively small points compared to the overall quality of the game. It’s clear how much care and intentionality has gone into its design, and I’m thoroughly enjoying it. Well done!
Thank you so much for the extensive and valuable feedback! I really like your idea about making Grid Integrity damage clearer, especially the forms quivering before they explode. That extra moment of impact would definitely help with clarity.
Hello again! I'm really loving this game at the moment and gotten super deep into the meta and strategies. I've played until epoch 66 and have written a list of some potential fixes or tweaks that could be implemented.
---------------------------------------------
Ideas
- New set of upgrades that buff constructs with levitate that are placed on an empty square or target/attack levitating forms (must have enough value to justify having to buy two upgrades for it to work)
- Ability to draw arrows before placing pieces
- Allow players to select pieces off their pedestals with number keys
Tweaks
- Highlight square underneath piece when hovering
- Difficult to tell how much health a construct has or how damage works (reticulated frame just says adds +1 reinforced but can be difficult to know what that means unless you are already familiar with the upgrade)
Bugs
- Promote has bugged one time, promoted pawn without meeting the requirements
- If the player exits to title screen immediately after their final attack that would result in a loss of board integrity, the next time they load up, they will start on epoch 2 and most of the board squares will be missing, however, the board will still be at 100%. It also spawns in extra forms that shouldn't be there at that early of a point in the game.
--I avoided mentioning bugs that are listed on Trello--
All in all, I've had a GREAT time playing so far. With it's stunning visuals and it's intellectual and polished gameplay, this game is truly, very impressive.
Thanks so much for taking the time to write this out. It’s awesome to see how deeply you’ve gotten into the meta, Epoch 66 is Wild! I honestly wasn’t sure this game even had a meta yet, so it’s kind of surreal to hear you talking about it like that.
I really appreciate the structured notes, I’ve added these to my Trello. The levitate upgrade synergy and arrow-drawing ideas are especially interesting. Glad you’re enjoying it, and feedback like this really helps me refine the experience.
The updated integrated tutorial is super helpful and much more intuitive. A major improvement on an issue that I had whilst playing the first release, making the game much more beginner friendly and significantly less daunting to get into.
Its actually pretty crazy to me how much a little bit of direction helps encourage players to read and learn about all of the upgrades.
Thank you so much! That’s exactly what I was hoping the new tutorial would do. I’m glad it’s feeling easier to get into.
Great game full of unique interactions and satisfying clears.
I would like the promote mechanic to rather avoid promoting into the same pieces as you have the drive/core of instead of getting rid of those upgrade cards.
Thanks so much! Glad the clears are hitting right. And yeah, Promote can feel a bit mischievous when it decides to replace your Core. I like your take on steering it away from that.
This has the makings of a fantastic Rougue-like and the bones of the game are fantastic with really satisfying gameplay especially when everything clicks together and combo's start stacking on top of each other. While chess is not for everyone Magnus is still worth a shot if you are a fan of Rouge-likes
Thank you so much! Really glad the core is clicking for you. Those combo moments are some of my favorite parts to see come together.
I really REALLY like the look of the game (rip purpur flowers 💔) and the flowers especially but don't ask why because i don't know. The only thing that might be something to consider is a pause feature? Maybe i missed it but yeah. I can imagine a scenario where I'd be playing but then I need to go somewhere and i cant pause/save (im not sure if the omission of saves and pausing is part of roguelikes so im sorry if this is useless info 😅). But gameplay is really smooth and i really like the whoosh sound effect each time time you complete an epoch!!
purpur flowers 💔 taken from us too soon. I promise there will be more flowers. Also, the pause button lives! I swear it’s there 😅😅
This game is a straight up masterpiece! The rouglelike elements allow different builds and strategy to try out and it is super unique being one that revolves around chess. Super interested and excited to see what this game becomes. <3
really cool aesthetics, i love the plants and pillars around the platform changing as the game progresses, and the sound effects are crisp and satisfying. I'm really bad at the game and couldn't get further than epoch 14 after playing for about 2 hours, but it's super fun :-)
Super addictive!
Loved the roguelike replayability and creative array of upgrades, sound effects were clean and matched the game well. Very creative take on using chess pieces as defesive mechanisms, makes onboarding super intuitive and easy to pickup on mechanincs.
Feels too clean and polished for a game on itch, was expecting way more bugs!
Haha! I’ll take the “too polished for itch” compliment. Thanks for playing!
Loved giving this game a try. It definitely took me too long to understand how it works(but that will happen if you ignore the tutorial). The game feel is incredibly polished, and the game looks amazing. Trying to strategize each round and figure out the best place to put your pieces was a challenge and a blast. Keep up the amazing work!
Appreciate it! Stoked you enjoyed it, even without the tutorial’s help 😅 Thanks for the thoughtful feedback.
