Hey, thank you for playing! You can toggle on fullscreen from the settings menu but you can't go back once you're in-game so I don't recommend it lol. Also, the player has a different velocity going up than down. I hoped for it to feel better, and it certainly does, but I don't know if it was as intended. You can play the Alpha_1 executable to see how it was by default. I added a few assists for jumping like coyote timer and jump buffering, as well.
