First the things to improve and then "How clipping affects the gameplay" part.

1st thing to improve - clipping arount these parts of any wall (idk how it's named)

2nd thing to improve - make it so you can't jump on the stones here

"How clipping affects the gameplay"
1. Smoother clipping may make aggresive plays more rewarding

If you make it so that you can walk against the wall at a 45 degree angle to the right and not be stopped by the door then it would make playing aggresive noticeably easier because you don't have to check if you will hit the door with your body and can focus more on the fight.


2.If you want to make this map more proffesional (Valve like) then you should make walls (clipping wise) less complicated

In human terms - make it so you can walk along the wall and not get stopped by it (not get stopped by the rectangle like shaped stones in this map's case)


3. Players like and WILL abuse every imperfect clipping if it gives them an advantage


4. Players like freedom (don't give them too much freedom)
