Great game, really interesting composition. There was almost some good counterpoint there, but it kinda fell flat, making an interesting idea repetitive and jarring. The mixing and instrument choice could use some work too.
I'm not sure why there was a sword and an axe, since the axe seemed to function perfectly well as a sword? I'd either specialize them more, or simplify them into one item.
The inventory system was neat, but it was a little strange doing some minecraft-style slot-scrolling to accomplish the relatively simple task of dumping a few logs.
The difficulty curve was a bit flat, I'd either make the fire die faster, at an increasing speed, or increase the threat of monsters to distract from the fire.
Ultimately, very good looking, and a couple systems were very well made. Cute as hell, and as someone else said before me the animated eyes thing does wonder for the game juice.
