It's cool to see 3D games here, but be careful with the optimization, the game performs poorly even with a good hardware PC, the idea looks very cool, but clearly there were a lot of elements that could add a LOT to the project! A main menu, a tutorial (even if the commands are just walking), a pause menu (I admit that we also forgot this in our project) and a little guidance, I didn't quite understand what I had to do, the only way out, me led into the darkness. Good job!
