I love the idea of the doors having traps and stuff behind it!
It makes it for a very fun and light game!
I think it would be cool to have the good doors to have special scenes behind them. Like someone giving you a power up. Or maybe they tell you what other doors are safe.
The only critical feedback I have on this is besides from using the powerups to prevent it I feel like the doors are too random. It might be nice to have tells. Maybe you hear murmuring behind the door. or a gun being loaded. Or scuff marks at the front of the door. And over time players can build up a mental map of what could possibly be behind those doors.
-- I think the tells might not need to just say it's good or bad (in a black / white sense), but maybe it could be a tell that it could be a good or bad. So that maybe they would want to strategize and just look for the definitive good doors first before they go for the more chancey doors.
Anyways, cheers, and good work!
