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!
