This game feels like it has potential, but there's definitely a lot of room for improvement.

It gets very repetitive fairly quickly. Perhaps having the enemies come from more doors, (and having different kinds of enemies. Maybe give him limited ammo so the game isn't so easy?)

A little polish goes a long way. Having the enemies flash white instead of just disappearing can make the game feel a lot better.

This is a great presentation to look at about how adding these little tricks to a game (especially a shooter) can make a huge difference! Start at around the 7 minute mark https://www.youtube.com/watch?v=AJdEqssNZ-U

Congratulation for making this game !
Can't say anything more than Mmoustafa ! SFX would have added a lot. Great work !

Nice start.

I'm gonna agree with mmoustafa. The game already had an interesting mood though, and you could definitely play with that some more :)

Yeah, it does have potential. I thought it was hilarious that those mobsters must have brought a freakin' parade to this guy's office, and the only logical thing for him to do is just mow them down (with a pistol, no less.)

Humor 5/5, if not unintentionally. :)
