here is the first first version of my crane simulator! it still needs a lot of tweaking and the models are crappy but i think it's already fun to play around with it so i decided to release this version.

<edit>

controls:

use the mouse and the cursor keys to fly around. emitting balls is still possible but i limited them to 50.

a+d -> rotate
w+x -> forwards,backwards
e+c -> down,up
q+y/z -> open,close claw (keep pressing y/z to hold something - i have to improve that)
1+3 -> rotate claw

now let's see if you are able to stack 3 stones! (stacking crates is easy)
