Basically when u force move the 'Character' Left or right, it has a bug. Aslong as its going right it stops at obstacles, but whenever its going left, it starts climbing up the obstacles.
Its not only on set position, but the same thing happens on bullet effect.
Press D untill u go left (mirrored) and see how it goes UP the obstacle with small jumps. Also happens with bullet effect.
Here is bullet CAPX -
Use left or right arrow. NOTICE how using left arrow makes it climb up the wall obstacles. Why is this?
