Really cute little puzzle platformer! The puzzles weren’t too hard, but they didn’t feel basic, either. I think you could get a lot more puzzles out of these mechanics - they’re simple, but work really well. I think the best part is the “two block rule”, which leads to some really interesting thought processes. “I can’t break both these blocks yet, because then I’ll be normal temperature and the spikes will come up…” You taught all the mechanics intelligently using level design, too, which was nice.
Nice work! I think this is my last game this year…
