Continuing this project

I'm pretty sure I'm going to continue to develop this project there are a lot of things I want to try with this engine. I have already started working on a new way of doing walls and getting off the grid. I want to try semi transparent walls and short walls and a bunch of stuff with walls. I also want to expand the enemies and add a bunch of stuff like hit-scanners, projectiles and bosses.  I also want to add a skybox for open areas,  the ability to set ceiling height in covered areas and pits that the player can fall in. 

I'll update as I go.
