The concept overall is a really solid one, but there are some issues: the text at the beginning goes so fast that I couldn't read it (I had to open the game page to know that I can change who I'm playing as), the "player" shoots way too fast, also the controls are pretty finicky, I would recommend trying out other fps games and comparing this game to them, what do they do and what you do, that way you'll have a solid point of reference. Keep improving, you're on a great track!
