The progression feels a little too slow for a game jam game . I died on level four, and really didn't want to try to get all the way back, but I also felt like I missed a ton of content. I'm guessing this was intentional, but every mutation seemed to make your character worse overall, so each pick was lose-lose, and the dash ability felt like it took too much time between clicking and dashing to really be useful.
The art has so much polish, with all the little animations everywhere, and the sound design is incredible! I think it just needed a bit more playtesting to really hone the gameplay.
