That was pretty cool. But man was it hard to get the hang of.
The art was really nice. The sound effects and music paired with it well. Everything gave off the tribal tiki vibe you seemed to be going for. The key pickup sounds were especially helpful because sometimes you just tried to fling the box all around the room and hope for the best.
The level design was well done. Having the starting area be locked off from the rest of the map was great. It meant that no matter how much you flung the crate around, it was still within that starting room until you figured out the controls (by that time you were ready for the rest of the map).
