Rough around the edges
First off, you CAN rotate the blocks. Press the up arrow.
Graphics: Not a whole lot of variety, but what's there is impressive.
Style: A tetris game were you keep a moron from killing himself? It's certainly a twist on the genre, but why save the little dunce?
Sound: Clicking and pseudo-explosions... meh. It's okay, but next time, maybe get something a little better. The line-clearing sound gets old pretty quick.
Violence: A kid shooting himself. 'Nuff said.
Interactivity: It's a game, of course it's interactive! Simple controls keep it from being bogged down.
Humor: Meh... I didn't laugh at it.
Overall: It's a good framework, I'll give you that. A bit of deth in some areas wil make your next project even better.
Oh, and a little side note... you might want to invest in a better translation software, 'cuz Google only works so well. Not that we can't get the general idea of your words across... there's a lot of idiots out there who only type in half-assed sentences. But you, at least, have a valid excuse.
