Always love the surival horde games. The sound effects crunch well! Stacking the wand to do some crazy attacks was satisfying as well. Was not sure why my wand would stop working and it took me waaaaaay too long to figure out how to unlock my mouse (was facing one direction for like half my playthrough). Also, not sure if the level has bounds but I think I ended up seeing the the default game-engine background for 2D games :P
Either way, good stuff!
