I will accept, at most, half the responsibility for this.

(It would be impolite not to give the source, or the other source. By "source", I think I mean "font of madness".)

Special announcement! I noticed after mocking this up that the game just has all its assets lying around in the data folder - therefore, the files for Hanano Puzzle - Hatoful Complete Birdie Edition are available now. (It's really just a ZIP with a PNG and a WAV in it - unzip it to your own data folder after taking backups of them both if for some reason you feel compelled to modify your game in this way.)
