I guess the game only goes to about the third level, ey?
Never did figure out quite how to really kill things or anything, not that it seemed to really matter. The little tech demo in the third level was easily the best idea of the lot, having to switch between the three types of lanterns to figure out where you were and how to get around. That definitely has potential, liked messing with that.
Only real criticism I have, in as early a state as this is, would be to just not have a brown character on a brown background. Placeholders or no. Other than that, good luck!
