Thanks for the suggestions!
- Properly gauging depth and perspective can be hard sometimes, I mostly rely on various tricks to get it right (some can be seen in my map tutorial). I haven't thought of a better way to assist this yet.
- Adding vehicles is possible but it will take a long time for this to happen. If it does, I first need to add landscapes and AI support for bigger maps, as well as networking-reliable vehicle physics.
- Changing walk speed / jump speed / gravity is something I have to avoid because the AI player calculations rely on these values being unchanged. I could allow changing these depending on the map (during map creation only, and for newer maps only). I will consider this.
- New guns are generally a big chapter I want to work on, I certainly will consider them but I prefer to prioritize other things first.
