Interesting concept. Making the screen dark allows the player to not get hit by projectiles, but they won't be able to see the turrets, which can oneshot the player if they run into them. And turning the screen light allows the player to see the turrets, but they will get bombarded by the projectiles. I also like the gravity switching mechanic. Game was hard to play at first, but once I got used to the controls and the game concept, I was able to clear it without too much trouble.
