I LOVE this! It took me a second to figure out how it worked, but when I did, I said out loud "ohh, this is fun"
Some of the platforming is a little tight, requiring a few retries and some tough timing to finish with the minimum possible keypresses. Loosening it up a bit would be fun, but the challenge is nice and certainly defendable!
A bit of text in game to explain the premise would be welcome, but that's really a nitpick.
Excellent work! Very simple with great execution for the limited runtime. I'd love to see you build more levels!
