This was a blast! It was very fast, with silly animations that made me giggle (like when I realized I was just a floating arm).
The movement felt a little floating, like I slide too far after jumping. A lot of the jumps seemed to require a crouch-jump, which is either unintentional or should have been explicitly stated.
Overall, the mechanics were straightforward, fun, and original. I plan on playing more of your games in the future.
