Update!
I’ve done few game design metric adjustments (currently the prototype is literally almost blank of game design), some code fixes, added some sounds, made doors a little bit better looking, cleaned up the initialization time and added a static loading screen, fixed lots of problem with Client’s enemy visibility (and there are still remaining I believe) and created a whole new enemy & wealth items (sarcophagus, urns & stuff) spawn system.
Next steps are NPC’s, dialog & quest system. Going to be a lot of fun 
A friend of mine told me that as well but unfortunately it is the one feature that won’t make it into my list. I won’t take the time to rebuild my current systems to allow gamepad controllers right now, and if I ever do I will just restart such a project from scratch which is not on my plan either. But it is definitely something I’m interested in and that I’ll keep in mind for the future.
