Are you talking about level 5 with the red and blue platforms? Yeah, that section is tough. Once you have lit the brown torch surrounded by the red fire enemies on the right, you'll need to stand on the blue platform with the second brown torch high above. However, you must not light the torch until the red platform below you has phased in, because if you light the torch too early or too late, you won't have anywhere to stand on and fall to the abyss below. I even died several times while trying to beat my own game, especially levels 4 and 5; I made those levels tougher than I originally planned. >_<
Thanks for playing my game!
