Download the drivers for this new, cutting edge trackball controller from Thwacksoft®

Included in Installation Package:

  • Driver for your trackball controller

I made this game for the A Game By Its Cover 2020 Game Jam in about four weeks. Being a big fan of alternative controllers, seeing the cartridge in the Famicase exhibition sparked my interest in designing an alt control game playable by anyone without the specific hardware. 

This game is released! Happy to make more levels if there's any interest.  Any feedback is greatly appreciated! For more alt controllers, feel free to follow me on Twitter!

Dude, do you actually need to use a trackball?

Anything can be a trackball if you try hard enough.. check out the opening cutscene 0.0

Umm, does it work on laptop

give it a try! Might have to have backwards controls 

Ouch. My Chromebook has a cover on it, Ill try and take it off


Highly recommended especially if you want to clean your keyboard.


this may be one of the stupidest concepts for a game i've ever seen... i love it, 100000/10


This is really neat, I love the concept of this being a demo game for the trackball, and those win 9x aesthetics are on point. The control scheme was a bit confusing at first since I was playing on a laptop and thus didn’t use the keyboard-ball combo, but I eventually figured it out.
