pretty fun! negatives and positives:
NEGATIVES:
only real bug i encountered is sometimes the hit detection was a bit off on the rocks and trees at the end. near the endgame, the rocks would sometimes stop registering i was hitting them by playing a sound effect when i was torching them.
not a lot of content here, which is perfectly fine.
unsure what the loss conditions are. can the enemies run the meter on the left to the bottom? Is that how you lose?
POSITIVES:
really unique roguelike idea! not only is the gameplay cool, but the worldbuilding is neat as well. I like the simplicity of "fight the ice, protect the fire". The day night cycle of combat makes perfect sense too.
if you build on this game with more enemies, weapons, an upgrade system, etc, i think you could make something people would buy to play!
show this to anyone you want to work together with as a project, i think plenty of people would be stoked to have a programmer who made something like this. great work.
