I tested this project as it looks quite interesting, but it doesn't seem to be working. I cannot mantle or wall run. I assume the yellow objects are for wall running but for the life of me cannot make it work in this demo. Jus thought I'd let you know. Good luck with your project though.
I love the lo-fi pixel look. The game is good. How did you get the enemy to move back when you shoot them? That's great, It adds impact to gun. I'd like to implement that in my game.
