Thanks for the comments. The camera lib is a modification of vrld's original lib. I am not the author of HUMP. The arrow keys to move the camera feels intuitive to me so I kept it like the original version. If I press right, the camera moves x+; if i press up, the camera moves y+, which makes sense in my head. You can change the sign in main.lua if you want it reversed.

Sorta what I figured.
Missed the discription of available controls.
At least the function of 'd' & 'k' are provided.

useful thing for me
