Awesome game, with nice art, level design and music. But the lack of checkpoints is really annoying. And for some reason, when the rocks were falling, it seemed like someone was shooting (the sound, I mean), but no one was I that was also annoying.
Thanks. I didn't have time to fix the sound system properly, so the rock sounds are way louder than they are supposed to be. I fixed it for the next version tho.
