I like the idea and since the walls are kinda huge it fits into the theme kind of. I would probably even try to expand on that feeling.
As for gameplay this game doesnt offer too much. Especially those long corridors where you just hold w dont make fun. In such a game i would increase the base movement speed to the sprint speed at least or make autosprint and sprint button makes you walk. And i would give the player something fun to do while moving. Like a good salto jump/dash or so. And more traps. Oh and i clicked on it since the beautiful thumbnail :)
