Really nice! The controls are tight, the graphics are great, and the concept of giving away abilities is a great way to interpret the theme and add replayability. I would love to see more variety in things you have to give up if you continue this in the future. Another thing that I think might add to this is you had an ongoing score that adds up on every consecutive run that increases when you defeat an enemy or end with extra time to increase the tension. This is a really polished game and I could see it being a full release eventually so I'm excited to see if you take it further.
