Interesting concept. There's a bit more Trial & Error than I would've liked, but it's a puzzle game so that's to be expected, and the consequence for failure is minimal. I am, however, disappointed in the lack of a proper ending. Getting the real "ending" shows a congratulations screen, but no conclusion.
That, however, is my only complaint. This is a unique puzzle game that I certainly think is worth the play-through.
Update: An ending has been added! And a pretty good one at that. Thank you, Junjo, for a great experience with this game.
