This is excellent and very fun! I am stuck at behemoth JR. though. he is always just short of dying when i run into some purple blocks and he catches up with me. anyone have advice? also, i entered the large room with the four pink bounceballs (in the second-to-last world, the one with green star/pentagram blocks), and a bunch of purple blocks appeared by the exit, then i couldn't leave. is that a bug or am i missing something?
