Cute game! Got 6:51 on easy any% and I've got some feedback.
First, switches are kinda picky. You can't seem to press them from an angle (either that or you need to be super close to them for it to register). It's tough when you're trying to go fast and they don't want to cooperate. (Edit: They're also a lot smaller than the usual DOOM switches, that's probably the biggest factor.)
Second, I think an autorun option could be cool. My pinky could use a break, ha.
Third, whenever the game has a lag spike, the camera sensitivity shoots through the roof. Even the slightest turn during one of these is enough to turn you around completely.
I'll keep an eye on the leaderboards! A little friendly competition is always fun. Keep up the good work!
