So i fixed some things

There were far too many collisionshapes in the tileset, and i didnt really like the ice-feeling movement on ground. 
Added harder friction on ground, 
added an initial move velocity when starting to use wasd from rest.

I also tried to fix the camera (worked for the character) but the background pixel art is still funky. i found a video that i posted in the wsu game dev discord that should in principle fix the issue
