I'm currently working on the 1.3 update for Gulag.
Right now unofficially I can announce that I've added: -Mines that can be placed on the battlefield
-Some new AI behaviors
-Final Boss functionality!
Eventually I am going to add a development page that shows more of the technical workings of my engine. Since I am ultimately doing this to find some work in mobile development, I think it would be important to show some code snippets!
