So, originally, I was going to have the gun and shield only work via just aiming the mouse differently.
Then I realized that would make the combat 110% more awkward. Maybe if I had set it up for controllers? But that is the root of the gameplay, and why things work the way they do.
I’m glad you liked that little level design flourish. Having Godot as a tool for building levels helped me do a lot with a few mechanics.
