Wow! loved the game. The graphics were great and I would absolutely love it if you chose to expand it after the jam. Two recommendations:
1. The running animation while recording was a little awkward. I would change it and make it more subtle
2. Having a quick button press to wither record or play. having to press E then click a button was a little annoying. Maybe use like e to record and q to play- IDK your game
Other than those two things the game was absolutely amazing! 9/10 from me
