Not recommended. Very little to do/change. The backgrounds change every few levels. The music is pretty bad as well. The modes that this game features:
1 player mode where you can start at level 0, 5, 10, 15, 20, 25 or 30.
2 player mode. Most notable for having brutal 7 hole random garbage(!). Oh, and Utada Hikaru is pretty good at it. :)
An option screen without any real options except mono/stereo, ranking and backup functions.
The vanish zone is visible in this game, and any piece spawned in it will overwrite existing blocks in it.
