Had a fun time playing this!
The movement was a tad confusing at first but once I realized I was launching the hydrogen I enjoyed the momentum and the sort of "spin-and-go" feeling I could create as I navigated the levels. Losing when you stop spinning when a hydrogen was in the wall was a bit confusing as well, but that became clearer with your game instructions and easier to deal with once I knew how to move.
The levels were fun!
I really enjoyed the music, props to the composer.
Well done on making your game!
