So, here's the thing about mazes; they don't allow you to make informed decisions, because normally, you stumble across the exit just by taking turns at random. Making my way through these levels feels more tedious than satisfying. For an easy fix, colour-code the switches and doors, so your player can think, "Aha! I remember where that one is, so if I can find my way back to it, I can get to the next floor!".
And yes, I'm not too proud to admit that Floaty McFloatface gave me a good spook.
