I love this game. So much I bought the GBA version and own 2 copies of this one.
Graphics- 7/10- Basic, but great, works better in a GBC
Game play- 10/10- Excellent. Simple, but really addicting. It's fun to attempt the last levels
Sound- 8/10- Some nice retro tunes, which were transferred into Dr Mario Puzzle League
Value- 8/10- Multiplayer mode, and it's really addicting. You will return to it I swear.
I think this is better than Tetris, so sue me.
