Is the game any good? I wanna try it, not because I want to be a cold-blooded school shooter (those fantasies are long gone, I swear), but because it sounds like a "good" representation of the indie genre. Feel free to debate its worthlessness here.

Never tried, but looks pretty lame to me.

I've finished it. It's more of an artistic indie effort than a serious game, but I think it's worth playing at least once. Very weird ideas.

Very true.
It's just like any other RPG Maker game, with a "controversial" theme.

One important hint: after you kill yourselves the game is not over, it's just beginning.

Unlike Execution!
