I really enjoyed the puzzle mechanics and level design of this game. I will say that the fire weapon could've had a better utilization for taking out enemies, as opposed to just making them faster. My final criticism is that the sound for the ice weapon and victory tune are a bit grating on the ears. I would suggest that you bring both of those sounds to a lower pitch. Overall, I found this game highly enjoyable with only a couple minor criticisms.
