Checking it out now. Expect some Donato first impressions soon!
(And I always thought it looked like a cross between Mr. Slime and Mega Man from the trailers.)
Edit: First Impressions
After finishing up all the starting levels with their own tutorials, here's my impressions.
The game does play as a stylus-only mix of the puzzles in Mr. Slime with the collecting of DK Jungle Climber and some light Mega Man shooting. Graphically, the cutscenes are anime-tastic and the initial character designs are cute. For the sake of "Moe" I went with Jenny. Unfortunately once you enter the actual level, your pseudo-3D rendered character is a bit squished and hard to recognize.
The other graphics, though, are very nice. The backgrounds to each world are excellently detailed and nothing beats climbing up a giant strawberry cake. One other aspect I appreciate is the ability to switch from viewing the stage sideways and holding the DS like a book to viewing them in the normal DS configuration. Sideways might be better to find the coins you collect as you climb, but the regular DS set up is a good break for your wrists every few levels.
Overall, I'd say this game is one of those special not-quite-ready-for-US releases that Europe only gets once or twice a year. It's not going to consume your attention forever, but it's a fun little diversion to keep around. It's release is perfectly timed as this is a great game to distract you a few weeks until the big games of September hit.
