Fun, quick game! Enjoyed it quite a lot. Gameplay overall feels very smooth and exciting. These are very slight suggestions / issues that I had noticed.
-Doors are a bit too hard to notice. When starting a level for the first time, I would just pass doors and finish everything and think, "What's left?" Should have a more obvious indicator, especially at a glance since the game is focused on speed!
-Shotgun doesn't feel shotgunny enough. I was using it like a sniper to two hit enemies.
-Sometimes enemies would clip into walls and tables visually. I knocked a dude down and he just, stood up inside the wall.
Very small things, and easy to miss out on cause of the game jam setting. Good work!
