Really liked the concept, cute art style (as you always have) and thight controls!
I did found a bug (I got stuck once at 2900 on the first wave, and the second wave never started for some reason, probably because I was killing some enemies off screen?) Also, I could not find where you say that a you can double jump, as I discovered it by accident right in the middle of the 3rd wave.
I would’ve liked to have the platforms rearrange in every wave to add more of a difference between them, but considering the way you’ve done the difficuly progression, it would’ve been just a nice to have. The waves, as they are now, feel different enough based on the enemies behavior (The ones that shoot at you just don’t have mercy in the 3rd wave, right?)
Overall, nice submission, Vim!
