The chess theme seems super interesting, I'd love to see it fleshed out a little more and play even more into the mechanics.
My biggest issue was that I had a very hard time telling when I was damaging enemies and when enemies were damaging me. Then again, maybe I'm just looking for excuses for how many times I died. At least it meant I got to see the cool health effect with the piece slowly breaking apart. That was super cool!
Ultimately, this game is just conceptually fascinating to me. Good work!
