Great music and a fun little challenging game, though sometimes a bit frustrating. I did not make it to the end, even on easy mode.
The first time my character missed a platform and fell, I found it weird that all the platforms below the current height of the screen unloaded, but still made the PC fall through that space. The pickup that launched the PC up was great until there wasn't a platform to land on, too. I also would have liked to have seen the theme play a role in the game mechanics.
Good work to the team on your first submission! I hope we get to see more in the future.
