Nice little idea, although, you might want to consider that fake walls, and spikes out of sight are not challenging, they are annoying and unfair, especially when they collide with your other mechanic of having to memorize the path to the exit.

Wow this was great, I do like how even if the mechanic is simple, it feels very connected unlike other games.

Interesting game with pretty neat death animation. A thing you could do to improve it, is adding a jammy soundtrack.
