For Leve 6: Increased the height of the first fire trigger and cease fire trigger, so the player can't jump over it using the edge jumping trick, skipping the turret section. Sped up the eyeball in the last room and raised it above the floor by 0.5 units. 

For Level 7: Added a floor reinforcement in the checkered patterned room so the likelihood of falling through the floor when you drop down from a higher ledge should be much lower.

For Level 9: Added floor reinforcements in multiple places where the likelihood of falling through the floors should be reduced.

For Level 12: Added floor reinforcements in multiple places where the likelihood of falling through the floors should be reduced.
