I've participated in games before, but this is my first time working on a puzzle game and I've already coded what I want the basic of my game to be:

3D Top-Down Movement, 2 Player Character Swap controls.

I'm having a hard time coming up with challenges and levels for the player.

I don't want to get too into the details yet, but add me on discord Kdpx#9624, and I can fill you in quickly.
