It just doesn't work. It's a terrible idea for a game. It's based mostly on luck. You should at least show the next piece, so you can plan ahead. That's what tetris did. That's just the bare minimum. The other is to chop those pieces into smaller ones, or to keep to 3 colors. You just can't throw a bunch of huge pieces one after the other.
Reviews for "Match The Hearts"
The pieces are too big! Since you can't turn them, if you get a space only a small one will fit thrum you're screwed. It needs more 1, 2, and 3's. When the pieces almost take up a half line, then you have to have a small piece ti bridge the two.
