As of version 0.2b, there's nothing very special about this demo, and there doesn't seem to be anything special about the game it promises, either.
Play some uninspiring minigames to raise your stats until you hit a high enough number to trigger the scene. See some good, but vanilla art paired with some fine dialogue to make a scene that isn't more than the sum of its parts. Be disappointed there isn't more.
Why have minigames that aren't fun or sexy? Why have so much dialogue (especially during the few scenes there are) when it isn't hot?
If you decide to give this one a try, I doubt you'll miss much if you just unlock the gallery and view the scenes directly.
