Right now I'm downloading a trial for the computer version of the game, and so far it's looking good. Anyone else planning on getting this when it's out on XBLA (some time this spring). Not sure how the controls will pan out though.
EDIT: Here's the supposed achievement list, courtesy of xbox360fanboy.com:
Beat the Basics-Complete lessons 1-5 in tutorial 1 and lessons 1-3 in tutorial 2. (10 points)
Time Bandit-Beat the time limit for 10 puzzles in Timed mode. (15 points)
Sampler-Complete 1 puzzle in each of the 3 difficulties. (10 points)
Super Sizes-Beat a puzzle in each grid size: 6x6, 8x8, 9x9 and 12x12. (20 points)
Natural-Solve 10 puzzles with autopencil and show errors off. (10 points)

These are looking pretty sweet, not too hard, but a few look time-consuming.
