It took me so long to figure out how to play this game, but once I did, it felt so rewarding! That said, I didn't realize the fire had an AOE until I skimmed through these comments (even though the first level makes it obvious), so I think a visual indicator for that is needed.
I think this game is seriously underrated; it's one of my favorites of the jam and I would love a full-fledged version. Fantastic job.
