Answer:
Frogatto! Perhaps the best eponymous free (on P.C. [supposedly there's an iPhone version in the works]) platformer of 2010. Brought to you by some of the leading minds of The Battle for Wesnoth, which is where I learned about this from <Tonepoet points to the Rocklobber>.
Yeah, I don't post here aallll too often but I know you
at least some of you guys like independently made 2D games like Cave Story and oh Touhou so I thought I'd post about this here since it really is a rather neat game, with beautifully detailed pixel art, a hint of quirkiness and lots of color. As for the playstyle Frogatto himself controls kinda like the title states, albeit a little more sharply and I never really did get far enough in Rayman to determine if that's anything more than a superficial resemblance.
It's not quiiiite finished yet but the first release cannidate is out today
sooo I'm guessing it's ready for the public, maybe? <Shrugs shoulders>
