This is a neat concept! A few things I noticed:
* This control scheme is very mysterious.
* The arrow keys and Z stop working in the options menu.
* There's no way to increase the volume in the options once you've decreased it.
* Because there's no "Throwing" state, it is easy to bonk your head on the projectile because you're still moving in a direction and it just spawns in front of you.
* There's a bug after the dog goes into the TV. If you time it right, you can throw the projectile, run into the far wall, and get stuck.
* Certain backgrounds make the projectile hard to see.
