Hey, Smasher!

Here are a couple of games that fit the theme: Switching Gravity.

VVVVVV: A retro platformer where you flip gravity to navigate challenging levels.
Prey: A sci-fi thriller with gravity-defying environments aboard a space station.
Antichamber: A first-person puzzle game that challenges perception with surreal, gravity-shifting mechanics.
And Yet It Moves: A puzzle-platformer where you rotate the world to change gravity and solve obstacles.

Happy Smasheroni!
