Yay! A fellow developer using Unity in this jam! Creating a 3D FPS shooter with enemy AI is ambitious for a first game, but you managed to complete it and that's amazing! (compared to my first game lol)

Although, there are some bugs you might want to fix 

• UI Canvas clipping through level (A render mode problem? Try Screen Space - Overlay?)
• Player getting stuck against walls (Adding a 0-friction physic material to the walls would be useful)
• Might want to lower down the turn & move speed (Quite hard for me to navigate and shoot the enemies because I keep over-turning)
• Enemies like to walk on top of the walls

Other than that, thanks for making this game, I hope you had fun while creating this!

Was it intended for the camera to shake and turn when the player collides with a wall? That seems to be happening for me. Also, the J and K buttons, which I assume are the "look left" and "look right" buttons turn the camera way too fast.
