A very nice, short game.
Its graphic style does somewhat call for it's difficulty, but it's neither too hard nor too easy. While I had little trouble getting through the gathering part, it took me quite some time to defeat the boss.
Its BGM also goes really well with its graphics.
I have but one thing I found annoying:
Most enemies, read: bats, are just above your attack. It made things somewhat more annoying to do, but hardly made it any harder.
