Thank you very much gutsmangbs for the feedback list!
I was thinking to have the camera more distant to the character when you are not aiming, and fix collisions with the enviroment. I wanted also to put a rifle in the second scene, but I had to discard it, I will put it in the next iteration of the prototype.I was worried about the level design, I could not make any playtesting with others, glad you did not have any issue with it.
It would be great having feedbacks from you on the next update! :D
