move around with zqsd, sorry qwerty users, you'll have to use this. look around/move with the arrow keys. move in horizontal/vertical directions with zqsd (I don't recommend this) toggle the sliders on/off with B on your keyboard.
I made this all by myself and didn't use any tutorials. I know it's far from perfect but it's something, right? the fish-eye effect is too hard to fix. btw, this is my first 3D game! =D
