I'll be honest, holding down the left mouse button for fifteen minutes isn't exactly my idea of fun. The flamethrower looked nice, but it needed to either melt the ice faster, melt more ice at once, or have less ice to melt in the first place. Or have anything to do besides melt ice, or at least have a melted ice meter on the screen so I can see my progress.
Of course, I never really enjoyed or got the point of the various X cleaning simulators that seem to be a popular genre on steam, so maybe that's just me.
Or maybe its that I've watched a few too many Outer Wilds lets plays lately, and had a subconscious aversion of running around in a field of ghost-matter looking crystals :]
