I absolutely love it. The cute design mixed with the fun gameplay and the fantastic level design makes a charming game that I can't wait to figure out how to get through the wind segment... BTW, is this a work in progress or is it completed? It looks completed, but maybe you're planning on adding more interesting mechanics.
You can finish the game and you can even get an additional ending in new game+. So I guess it's completed! :-)
For the windy part: Do you have the glide ability? And did you realize that the yellow buttons change the wind direction?
Everything else is more or less hard plattforming and climbing.
