Whenever a shotgun beam hits a wall, there is a brief delay before it gets reflected off the wall
Since the Shotgun is an automatic weapon it can be held down to shoot indefinitely, which also allows you to directly shoot on unfreeze
The beam does not in fact drag you in the direction it came from. Instead, it pulls your tee towards the origin of it, so either where it was shot from or from the last point it reflected off. This is also the reason why the advanced indirect shots work.
When two tees overlap, the use of Shotgun will bring very high speed, which can even pass through the stopper.
