That's a nice idea but it's probably too hard currently :
You don't have enough time to react against the enemies, it makes it very hard even without the sleep paralysis. The game isn't very forgiving as well, you get attacked even at the very start of the game which forces you to dash instantly and glitch outside the screen.
Since the gameplay took so much of my attention, most of the time I couldn't even notice the change of state before it was too late, it would require some impactful feedbacks for it to work properly, like something that changes the color of your screen for a short amount of time.
