For Leve 6: Changed the eyeball obstacle a little in that long room with a key at the end by speeding up one eyeball and flattening the electric field around it, and moving the other eyeball to the final room (and speeding up that one too). 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.

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 11: Decreased the time intervals in which the ice cream shoots ice cream cones from 800 frames to 770 frames.

For Level 12: Increased the HP of the Spikey Honeycomb enemies in the 3rd and last rooms from 1 to 2 (Like it normally is). Increased the HP of the Bibler Boss from 8 to 12 (Like it normally is). Increased the HP of the Mr. Bouncy Boss from 6 to 9 (Like it normally is). Added floor reinforcements in multiple places where the likelihood of falling through the floors should be reduced.
