Very difficult game. The pace seems a bit slow, and the charging time too long, but that's not necessarily bad.
I couldn't really pass more than 400m before I quit, not because I was bored, but because there are too many games to play in this jam, but I'll come back to beat it.
Mine is also a only one input game. Here's it is you can spare some time playing it. Many Thanks:
