Right, here’s the secret for getting a VERY high score in Jolly Jugglers (4000+):
Go through the entire game as usual, getting as many lives as you possibly can. Once I was very lucky and got about 10 extra lives, which is rare but exactly what you want to have. Get to the seventh level, the last one before the boss. Now this is the first important bit: do the entire level, then LOSE rather than going to the next level — be killed by one or both of the PURPLE Slorgs at the very top platform, next to the portal. If you shoot at one of the Slorgs, be sure you do not have a weapon powerup, so that you don’t accidentally kill both of the Slorgs and leave yourself no way of dying. I do not recommend killing either of the last Slorgs, as sometimes bugs occur, and one shot can kill both. This will cause you to throw your computer out of the window, which is altogether undesirable. So don’t shoot at either of the last Slorgs.
