This game is really fun and creative! Having to empty my inventory was funny and I totally ejected some important items...
I really enjoyed the flute sequence. I had to figure out where to actually hit the note though, at first I was anticipating maybe I had to hit the note when it hit the top of the flute pan before I realized thegoal was to press at the line.
I also like how the flute performance then corresponds to the boss evolution. For the boss fight itself I was able to defeat the boss by doing a small circle in which I was able to just keep hitting with no damage.
