If the game lets you do it, it's not cheating. Everybody can exploit the same bugs/features in the game.
Having said that, I could consistently hit between 80k & 81k on level 1 by rushing through, grabbing only the power-ups on the way (including the fricken laser!!!), getting only enough comrades to exit, & killing the boss w/ > 100 seconds left.
So, you could have hit 380k, not 370k!

PS--what's with all you guys pulling a jasonbar & popping up scores at the last minute!?!? I'm simultaneously proud, flattered, & annoyed! ;P
