I'm afraid I couldn't play much of this game, the aformentioned high sensitivity combined with the psychedelic background makes me nauseaus. I'll grant that it's nightmarish, but it may be a bit too literally so. The models were nice though, for as long as I could see them.
Also, the controls listed on itch.io don't seem right. WASD does nothing, only up and down arrow work for movement, but left and right arrow don't strafe or turn.
