Typical crappy demo
Good idea, a block switching game with a twist, but as with most flash demos, the game cuts you off right before it might begin to get fun.
Honestly, does it work? Does anybody actually buy the game? Who the fuck pays $20 for a flash game?
Personally, I think that flash games put up for the sole purpose of trying to sell something shouldn't be allowed, or should be in a different section so people can avoid them.
