One of the reasons of the projects is that there are a lot of J2ME projects that are ”death” and the authors are not more intentioned to keep the midlet updates (e.g. SecureMessenger, jtReversi, …) or add common functionalities (e.g. internazionalization support). Another benefits is that all the applications will share the same “core” libraries in order to keep the size/resource limited (especially in midlet suite bundle) and are tested on real devices.

Bubblet is a small puzzle game. You can move a cursor across the screen and dissolve fields that have at least one neighbouring field with the same colour. If you dissolve fields, all fields above that position will fall down. However, there is a Highscore. For two contiguous fields the Score is 2, for 3 it's 9, for 4 it's 16 - you get the idea. If there are no more neighbouring fields the game is over and your high score is saved.
