The concept behind this is really good, especially the bashing part. The graphics and music are awesome. My biggest gripe is the difficulty. I think one of the main things that makes it hard is the jump. At the speed the player is moving it is hard to jump before the player leaves the platform which make the long jumps really really hard. Making it so that you can jump for a few milliseconds after leaving the ground would probably fix that problem.
Other than being really difficult this game is really good and definitely has a ton of potential if you make it a bit easier at the beginning. Great Job!
