I'm big fan of this game, and I really hope it won't be abandoned after the jam, as it have a lot of potential. I will love to see it as deck-building rguelike.
Use of chess is very clever, as it makes understanding enemy movement more intuitive, wich is almost always a problem in this types of games. I also need to say, that the details, like changed player sprite when you hover over different attacks, add a lot to the game. Sound design is also very good.
Finding anything bad about this game is really hard, even my unusual screen resolution worked well with it, which isn't a thing even in my own submission. The one thing that could be added, will be indicators, wich enemy moves first, as they can block themself, but its just minor detail.
I love this game, great work!
