Hey SharkFinFace! Thanks for the criticism!
I'm new to the Unity engine, so this is actually all great feedback. The hallway is long for a purpose: there are some texts you can find throughout the hallway that slowly reveal a message, but I should try making them more obvious.
The whole "can't press the quit button thing:" I did not realize that. I did not have enough time to playtest, so I didn't find that.
I will work on making better models for my future games, but some of the stuff I'm not finished with may still look kinda like that, but I will try experimenting with other textures and skyboxes.
Thank you for the criticism, this will help for my future games. I do not think I will update this one, but I'll add this kinda thing to my unfinished games.
