The art style is amazing!!!!!! The feel of the game is great!!!!! But the first level seems broken. After you enter the room and pick up the shotgun and look back nothing happens at all. Loved the idea and the hand animation and the sound is perfect. That gun sound is great really immersive. But, sometimes the inputs from my mouse and keyboard are ignored completely. Overall it was faulty but it does have potential. Keep up the good work and if possible notify us when it's fixed I'd love to spend time on playing a Doom original-inspired game. It is my first time making a game. But, I am a very seasoned gamer and a software engineer for a few years now so I understand how tiring it can get. But you have a  great future ahead of you and if you have been in the industry for longer than me then we can easily see your experience. Great Job!! Just work on the issues and I'll love to learn from you and to play your games. (P.s. I think if you added your own idea into this it would spice it up. People have seen so many flappy bird and pong knockoffs. So having extra twists makes games more appealing.)
