stage 9: correct error: instead of far jump, drop down and normal jump
stage 13: Freeze the ball and Skip the gems in level 13 for an additional countdown skip
stage 14: dont drop down but jump at the start (like Reboot)
stage 22: stopping the piranha. pick up a candy and a clock. (Idea: Candy stage 10, clock stage 21)
final dragon disappear glitch? see MightyMike's run
maybe to be updated in the future.
Update: Stage 22: U can skip the piranha without stopping the time.
stage 13: Freeze the ball and Skip the gems in level 13 for an additional countdown skip. This is possible. It's hard to get to 100 by stage 25 but it is possible. You can miss 1-4 gems total from 13 to 25 only!
The risky part is end of stage 15, it helps a lot if you can get 1-3 gems in the last jump.
NOT A TIMESAVE. stage 32: jump over the first 2 piranhas from the fire pillar and land on the 2nd platform and it might be faster, triggering the invincible enemy earlier.
-> Does not save time because the piranhas spawn the same time still in both methods. The piranha is the limiting factor. But if you had a time stop....
