This is a pretty fun map but has a couple tough tricks.

Using imp to stop door from closing saves 25-30 seconds. If you get him angled right he can come down the elevator with you first try too. You can use the hellknight for this too but I think the imp is a bit faster.

You can grab redkey through the wall instead of doing an intended jump.

And to end the run is a direct route to grab blue key instead of dropping the platform.
