Uses a new glitch called Jump Storage that only works on older versions (DM Infinity and before). If you touch the level exit while holding jump and keep holding until the bonus run starts or the level complete screen appears, the character you did the glitch with will keep jumping upon entering the next level. This lets you preserve airjump, use it in places you wouldn't normally have it, and means you don't have to refresh the page as much You can play old versions of the game by going to https://www.bbc.co.uk/childrens/assets/games/cbbc-dangermouse/X/index.html but replace the X with any number between 14 and 203, which gives you different versions of the game. DMSTD is the fastest on versions 21 through 75.
