Really interesting game! The Paper Mario style was cool to see, and some of the mechanics like the tongue where awesome, the wall jump was nice but sometimes it got stuck too much into walls.
The levels where also very expansive, which was really cool with its multiple paths but this was also a problem sometimes because of all the backtracking, but the live map system was great, it only missed the player location on it (maybe I missed it), but the biggest problem was the camera angle, I dont think that the angle per se was bad, but how far away it is, it seemed to be clipping outside the scene a little bit.
I only wished that the tongue mechanic was used more, since the freedom of movement it gave was really fun, and also that the player had a shadow to judge where he would fall better.
Overall this was a cool and complete experience with a very nice "paper-like" style, with only some problems in the way, great job!
