This was good fun! Very simple but still takes some time to master. As with a lot of these single button games, this would work great on a touchscreen, would be very addictive as a mobile game! And you could even have different characters with different thrust speeds, weights, and thruster rotations.
The ceiling felt a bit low, the game seemed to give me the impression I might have more vertical space right up until I hit it. But overall, great job!
(if you have the time to check out our game that would be awesome!)
