Fixing the base project

Hi!

I'm still here, I was absent due to work and other responsibilities, but I'm here. I decided to check the project again and did several refactors and change the project structure for something that makes more sense.

 The functionality is still the same (most of it). I plan to tackle the easier stuff, thus, I'm tempted to build an inventory feature that allow entities in the game to collect, store and carry items around.

As always you can keep an eye with the game's progress here, also join the Discord!
