Atari is gearing up to release Trioncube, a "kawaii" (Japanese for 'cute' or 'pretty') block-based puzzle game, on DS in June.
In a concept that sounds somewhat similar to another awesome DS puzzler, Meteos, you have to chain-up three or more blocks to propel your ship through space. The bigger your chain the more effective your thrust power, and the further your ship is blasted through space.
The idea is that you're playing as the captain of the ship, and you're travelling across eight worlds to rescue a princess from the arch villain, Hell Metal.
Trioncube distances itself from "traditional" puzzle games that have you clearing fields of blocks, and if it's anywhere near as fast and fun as Meteos, it could be something to look forward to.
