Definitely hard to understand, though that can be okay if it's deliberate? I think it would have benefited from a little more feedback on what was going on, though, both in large scale things like "what is interacting with these enemies doing" and the small scale things like "should I be able to walk through this boulder"?
The animated spritework and detailed (though large) interface were nice, and the music was a neat bop that didn't get repetitive, so overall a solid entry, well done!
