I really like this game's aesthetic! There are a few things that I'd like to point out though:
- The game over screen doesn't work, the cursor should be unlocked when this happens.
- The player model clips though the camera in first person view, so I'd recommend just making the player invisible in that case (the player should still be visible in third person of course!)
- The enemies have weird AI and pile up easily in certain areas, I'd recommend making them stationary since they can shoot you.
- The rewind mechanic doesn't have much use, there should be a point were you are required to use it at least.
- The music choice, the 3D models and UI and really good though! Especially the 3D art!
- The character/enemy designs, story and ending are really cool too!
- The character has very strange controls in the final level.
Aside from that, I enjoyed this game!
