Hi, thank you for playing this game!
Hi, what kind of bug did you run into? Maybe I could fix them.
This is a pure physics game. Sometimes the physics engine just breaks down (spinning wheels, not enough 'force' in the wheels to turn something connected, etc). These things are very difficult to fix without an overhaul. For me this game was a proof of concept for 'pure physics' but due to these mentioned issues I stopped developing it.
