I sense some potential here. I can see that you put some effort into this. I give points for effort put into this wad. You some basics of making levels, good job! However, you forgot one of the most important things of all levels. The thok barrier. It prevents Sonic from double jumping through walls, and makes it so Knuckles can climb the walls right. To make a thok barrier, create a big sector around your level and give it the same floor and ceiling heights. Example: floor=100 ceiling=100. It can be equal or below to your ceiling height.
You crossed a lot of linedefs with each other. This can result in the map looking just plain messed up. Just remember to never put a sector so it overlaps the other.
The map was far from good, but unlike most "bad" maps, I had fun with this one! It was actually quite amusing to play.
