I liked the concept of the game! Especially since the button will be used in different mechanics. The presentation could be bit better, and I got softlocked/stuck few times and had to reset the level via menu.

Also your game contains Quit Game button but it is a browser version that don't need one? Pressing that just makes the game stuck.

Overall good entry, I played it through. I liked how the final levels started to "build upon" the previous levels.

is the cover art made by AI?

I like the concept of this, it really makes use of the limitation of one button well and  gameplay was smooth. Though it would be great to have clearer icons for how each status effect works and that they're displayed in a way that's noticeable because I didn't notice there were symbols until I was already starting the level that has different status effects in it. For example, instead of triangles as arrows for the gravity up and down effect, it could be the traditional arrow like this ↕ or separated arrow version of it. Overall, great work!
