Ah, damn, that's strange. But lemme know if changing the sliders help! As for tips, not many I can think of atm. But I'd say it's recommended to wait for DoodleBob to go the other way before moving, so if Doodle Patrick is in your path, waiting him out won't be as dangerous. You could also watch a walkthrough to see how others beat it if you wanna see their strategies as well!
