I couldn't return to the game after attempting to adjust the graphics settings, that seems to be a bug as the "return" button simply did nothing.
Unfortunately, my computer isn't high-spec enough to play the game properly on it's default settings, it just becomes far too laggy. That's not your fault, so I won't vote on this one, but if I'd been able to play on lower graphics settings I might have given more feedback.
The art, music, and concept all seemed pretty cool from what I could tell.
