Super cute! The 'winter to summer' bubble effect is awesome! Story is simple but fun, I loved rescuing the little wiggle worm guys and gals!
Basic controls and jumping felt great, but I had a lot of trouble getting the wall jump to work consistently. Enough so that I haven't been able to complete the game because I got stuck on what looked like an area where I supposed to jump back and forth between to two wall to climb up to the next area. Sound like you have already been working on this though. Which is awesome, because this an otherwise fantastic game! :)
