This game is gorgeous. I love how every character has different attacks and movement options (Backburr is my favourite).
I got this error https://pastebin.com/cpu5xXtn when I tried jumping from a Noogie to a BuckaChucka in the second screen of the first level. Sometimes the character gets stuck on a corner and seems to float in midair (happened twice in the level where you have to jump under a rock to get across a pit. Other than that, the game runs smoothly and without any problems.
I wish this demo was longer because I had a great time! Great job! Keep it up!
