Nice idea. To be honestly , I didnt like the post processing effect. (I think wold better if you eliminate it).
By the way, I would like if possible you check my game. (Back to the dooms hell). Would be nice if you could give your feedback.

post-processing just gives it a modern look, i prefer that way. yeah i will check out your game.
