This one took me a bit of time to get the hang of, but was really satisfying once I did. Once I saw the G and the M - I realised what the next two levels would be too :D
It feels a bit clumsy to control, because the input is triggered on space RELEASE rather than space PRESS. I think if you swapped that it would be a lot more responsive. Also, it's really satisfying to get lots of bounces, but you're punished for bouncing too much because the ball despawns. I think you could benefit from a few more bounces allowed.
You've got a cool idea here, great job!
