I like it a lot - I especially respect the hell out of creating your own assets, and the music you chose also works really well.
Unfortunately, the game kept locking up on me. Usually when I hit an obstacle. It would progress to the part where I should choose if I retry or go back to the gym, but with nothing clickable:
Example of what the frozen screen ended up looking like.
You hit the theme really well, and what I was able to play was enjoyable! Good work!
