Quote from BluBotL:
The Jingaling glitch - when you reset during the cutscene where Jingaling opens the gate in Bottles' house, it saves & quits but when you load the game, you start from Jingaling's palace just before the B.O.B. cutscene. It saves about 10 seconds (the gate opening and leaving the palace). You can also reset during the level opening cutscene right when you see the beam come out of the roof, and that saves you a couple of seconds.
You're actually allowed to use reset instead of S & Q? I didn't know that! That's quite a lot of time you'll save just from the puzzles.
