A jaunty, fun game on Ubuntu! It would be good if the cursor were locked to the game -- I keep dragging outside the window, which confuses it. The persistently chirpy music makes me smile.
It's been a crazy year, not a lot got done for Wheely World but I've FINALLY found some time to add full screen mode and controller support, linux uploaded minutes ago.
Hopefully full screen will help your dragging issue but if you have a gamepad I'd recommend trying that, tonnes of fun :)
