Map extension, light polishing, controls recoding, just want to know how long this title can be and how it looks

"Completed" the scenery and went forward with controls code and more.

The ball is having less power when close to walls and I can't understand why. You can check it by just standing close to a wall (but don't touch it!) and jump.
The fun part is that sometimes this does not happen! It must be some setting in the physics of course, but it must be something counter-intuitive. This way, it's completely unreliable, I absolutely need to find where the problem lies.
