Glad to see another mouse wheel game (ours is also one :D)
I found the audio and level design nice. The theme also is really funny!
Some things I would add/change: The mouse spinning also after I jump makes it really hard to plan jumps, also I got stuck a bunch of times between platforms, I think there could be a mechanic of getting stuck sth like the bombs happening where it would make the mouse wheel jitter and get out of that stuck place, or to have checkpoints. I got frustrated being well into the game and being stuck into to platforms and having to restart from the very beginning. I think also the bomb mechanic is good that is there but I would add a certain jump and acceleration mechanic to it, like what is happening now but sometimes in a direction beneficial to the player, so the player takes the "risk" to lose some money and go on them in order to advance the level faster. Also cool game title :D
