could use a heat exchange view so we can see where heat goes and in what ammounts to help us work out ideal paths for heat to take but otherwise good game
could expand into user-made obstacle maps... it's fun but doesn't last that long, with obstacle maps you could modify the current unique levels to make them harder, more of a challenge...
so err, I checked what time warp would give me about 11 hours ago, it said 40 quattortrigintillion, right now I checked and found out I earned 37 quattortrigintillion in this time... looks like time warp is a little broken right now (seems like it's not 24h as it was originally but 12h)
