Wow, this is incredibly polished! The player character is absolutely adorable and his walk and jump animations are delightful. The cel-shaded art style and its pastel color palette are lovely, though like below commenters I had trouble with depth perception. Excellent 3D modeling work, though--absolutely everything is pleasantly plump and geometric! I found the controls a tiny bit slow and stiff, but I appreciate the laid-back pace of this game, and I appreciate that you didn't punish certain platforming mistakes by sending the player back to the start (though I kind of wish this were the case for the snowball!) Also, the music and sound are suitably soft and gentle--really nice.
I agree with below commenters about the camera locking up, but I still had a good time with this game, even though I got hung up on a platforming section and didn't complete the entire thing. Excellent work--this is wonderfully appealing and amazingly complete!
