Thanks! Yes, it is GLES2. I had wanted to use Godot 4, but the GridMap node was giving me some very buggy behavior so I downgraded to Godot 3.5.1.
You're the second person to mention the camera being inverted. I guess I don't play enough modern games. A lot of the classic games use the inverted camera and that's more what I was referencing when I was building this.
Thanks. I rigged the models in Blender using Rigify and the animation was done by hand using keyframes. If you use Rigify, you can also reuse animations between models using Blender's Actions system. The models and some of the animations were actually done a few weeks before the contest for some YouTube videos I was working on. I was originally planning on creating new models and was using them as temporary stand ins, but ran out of time.
