I think the art is really cool, I like that you used D20 dice instead of normal 6 sided dice. I tried to click the How to Play option but it didn't work, so I played it like a regular platformer and got stuck on the big yellow platform. I think having different characters is interesting but I didn't know what each of them did. I also felt like the hitboxes for the spikes were too big because I kept dying on them when I didn't think my character touched them at all, which made it almost impossible to make that 4 spike jump.
