I loved the idea of a chess roguelike and i think your execution of it is almost flawless. Stylish artwork and cool sound design immediately charmed me from the get go. I like how the color palette changes in every level. I liked your approach for not using text for anything but shapes instead but this choice also caused me to not understand how some of the mechanics in the game work. For instance i understand that the color circle shows the turn of enemies with the same color only when i read your comment below :)
The farthest i could go in the game was level 8 and it was pure luck. Most of the time i get killed at level 5-6 :) Game becomes very challenging starting from lvl 5. Combat is very engaging and requires tactical thinking. I love that i have to calculate my every move like an actual chess game. Game is pretty addictive and fun to play. I think i'm going to play it to completion. There is a bug in the game where the enemies can walk inside the walls and they cen go through walls. Another thing is that the number of enemies spawned starting from level 5 is i think i a little bit too much. It becomes exhausting at some point. I played the jam version, maybe it's fixed in the post-jam version.
I think it's an excellent entry to the jam and i'm really glad that you joined!
