Really great game so far! There was a lot more content then I originally thought with having multiple levels and different enemy types as well as a bit of searching to progress. The bugs I noticed were pretty minor; The player would get stuck on top of objects (lamp, bed, door) and unable to jump off, items would despawn in the sewer level and the frag grenade..... don't pick it up. Game play with the character was great, satisfying kills with every head shot, numerous selection of guns to use. I was wondering if you would consider having the lighter equip to the left hand giving the right hand an option for a pistol or knife allowing the player to still walk through the pitch black staircases and hallways with a weapon still attached? Something that could help if this makes killing the enemies to easy is to increase the amount of health the basic enemies have with body and limb shots.
The music was such a banger as well man it would be great to have something in the background or just some ambient noises as well to fill in the empty background.
Good luck on the updates and I hope this game gets you somewhere! There is definitely a lot of time that has been put into this project!
