Congrats on releasing your very first Unity game—getting a full 3D build out for a jam is a huge milestone! The loading screen setup, overall visual style, and music build a solid initial impression.

A few quick unity optimization & QoL tips to help smooth out performance for your upcoming update:

- In-Game Objective: Add a quick 1-sentence prompt on startup so players know the objective right away without having to read the itch page.

- Mouse Sensitivity: Add a slider or lower the default mouse look sensitivity so aiming feels less twitchy.

- Performance Baking: As Crabguy mentioned, baking static lighting (Lighting > Bake) and enabling Occlusion Culling will drastically boost FPS by reducing real-time draw calls.

- Static Batching: Check "Static Batching" in Project Settings > Player to let Unity combine non-moving meshes automatically.

Solid first step, keep grinding! If you get a chance, I'd really appreciate your feedback on my solo jam project as well: /jam/brackeys-16/rate/4953523

The game started off strong with good music and loading screen, and I liked the visuals to. There were some problems, first you didn't explain the objective in game it is goof practice because people usually don't read the entire description of the game. Second the mouse aiming was too sensitive. Third and more importantly the game was laggy I know this is you first unity game saying that this is impressive I couldn't relses my first game because of lag. A couple of things You could have done to fix the lag (it wasn't that bad) was bake your lighting I don't if you did that and let the lights on mixed, but if not windows---Rendering---lighting. The second thing you could have done (I don't know whether you did any of this or not so I am just telling you stuff that will help in case you did not) is bake you Occlusion windows---Rendering----Occlusion. Last in player settings (Edit---project settings) turn on static batching.  All in all, it was a good experience, and I would consider paling the next update.
