Help with my game

Im new to this and was wondering if i could get some help with walls. In my game you are on a spaceship so i need to make space restricted. My left and upper walls work but not my right or bottom walls. Also i cant seem to get the character past a certain point in the upper y axis. Any help will be appreciated.

I can’t see it now but…
-Is it solid?
-Is there a sprite for the wall?
-Is it enabled?

I know about the y axis limit, it’s been there. you can only make the scroll go left, right, and down.

whaa? I can scroll up, the number just has to be a negative.

same with left

huh. It works for left for me, but not up. It’s weird.
