It's great that y'all were able to get something submitted in such a short time span! If you end up revisiting the game and want to improve the gamefeel, I'd recommend looking at the Camera2D node's drag margins. They can be used to create a dead zone region for the camera where the camera won't move unless the player tries to go past the limits of that region. As of right now, your camera moves with every single movement that happens, which kinda makes it feel like the level is moving around the player instead of the other way around.
Good job and congrats on your first submission!
