I'm enjoying Incoboto. I think it's iPad only. People will be quick to make a few Mario Galaxy references, in that the 'planet as a level' structure is in play and there are a few gravity tricks thrown in here or there, but it's more a puzzle game at heart. Puzzles involve some platforming, or getting devices on each planet to function and/or work together. It's also got a nice style to it, though I have yet in my (admittedly early) play to see too much variation.
You are a little dude on your own little planet when you are visited by a 'sun', who references danger on other planets. You follow him through 'gateways' to other worlds, which are all seemingly dead with only remnants of their population left behind (which serve as game hints). There's also signs left behind by some mysterious "Corporation", talking about the (now non functioning) technology you come across along the way, which can be a little funny.
Control is pretty straightforward thus far, you move left or right by pressing either side of the screen as you 'rotate' around each planet/stage. You jump by either tapping high or doing like a slide/push upwards. So far it works pretty well and I haven't had any problems with control.
