I've made the world's first Blender puzzle game (I think)

Some handy tips:
When you turn on rendered view and wait for materials to compile, the number often freezes until you move the viewport around slightly.
Tips are on by default. There's a reason for this. Turn them off only if you are very experienced with Blender.
There's a workspace along the top called "Accessibility." In here you can choose colors and brightness that work for your vision.
You can't click on most objects in the game. Therefore, it's a little hard to orient yourself like you usually do. I recommend turning on "Lock to 3D cursor" in the "N" panel of the viewport. Then you can Shift+Right click to place the cursor anywhere and pivot around that.
Otherwise, remember that 'period' on the num-pad centers on an object.
You can't use transform gizmos in the game, because they don't work while the timeline is playing. Press G to move, R to rotate, and S to scale.
When rotating something a bit off-axis, it's easier if you press R twice in a row, to active gimbal rotation.
The game doesn't work while paused. But it's okay to pause to go to the bathroom or something. Just remember to start the timeline again when you come back.
