Nice little game.

The only technical issue I see is with the layer switching.

The staircase right after the begining, for exemple, always place the character object on the layer of the staircase upon reaching it.

This makes it so if the left arrow is pressed, the player will always go up and not back the way it came. That is unless the player goes up a few stairs, go back down and then go left.

Instead of an instant switch on entering a trigger, an UP/DOWN input would solve the issue gracefully while adding just a bit of depth regarding the interaction of the player with the game world.

Nice play on the genre.
Feels like a solid little game for the most part.
Good, simple visuals which help keeping track of what is on the screen.
I like the sound design too, I don't know if it is an original, but it feels right for the game: Spacey-ish and non-imposing. I think it is a good balance between what we expect it to be without falling into the cliché sound design of spacecrafts.

If anything, adding a visual queue or what not whenever the spaceship gets out of the camera FoV would be much appreciated.
Maybe it is just me, but I lost track of the spaceship a few time and, before realising it, I had died outside the bounds of the screen for unknown reason.
