Copy Kitty is an indie game (currently in Early Access on Steam) by Nuclear Strawberry (Azure and Raibys) that I chanced on almost two years, two months, and three versions ago. Given the gratuitous explosions and rainbows, this was very clearly the game for me.
Normally the game is a platformer with shooting elements; the object of each stage is to destroy all of the target enemies. Savant, the main character for whom the game is NOT named, breaks all of the rules by floating, teleporting, and generally being hilariously overpowered at the expense of being really complex to control. The result is a very different experience that has potential to go really, really fast.
If you're wondering why there's a blank space off to the right, that's where the annotations are supposed to be. Turn them on, although I guess you're out of luck if you're on mobile.
