The strength of this game is the central mechanic of adjusting the dials, and the large number of clever puzzles built around it. I genuinely enjoyed teasing my brain with these puzzles, which were challenging but not unfair. And there is a surprising number of levels available! Impressive.
Unfortunately, the presentation could use a lot of improvement. The graphics are unattractive, and it should be noted that the visuals for the "coldest" setting doesn't really suggest it, because ice is generally white or light blue, not deep blue. There is no music, and the sound effects are rudimentary. You might want to consider making a few more blips and bloops for jumping, adjusting the dials, reaching min/max temperature on a dial, etc. The presentation doesn't do justice to what is really a very intelligent puzzle game.
