Just finished the game and in all honesty, I enjoyed it. I didn't have issues with controls as others are stating, but then I'm used to old platformer type controls, the game was easy with a few moments of frustration but overall not bad.
It is however quite short, I completed it in about 3 hours and that was playing quite slowly and really taking in the beautiful artwork, etc. All in all bought in the sale, worth it at sale price. Probably worth it at ordinary price too but reiterating that its quite short.

Side note, when the hell did games become so achievement giving! Felt like every step I took I got an achievement XD
