futuristic vehicles collection

Here's a collection of three future themed vehicles. I'll probably make more improvements and vehicles eventually. Please like and comment!

0.0=release
0.1=fixed a bug added title screen and removed divider
0.2=x-cavator beta added and you can now switch between vehicles by hitting S
0.3=improved xcav. Movement slightly and lessened the # of buttons
0.4= improved xcav. Function and added course for it
0.5=xcav now works much better and bulldozer has a tall mode, the crane bugs have been fixed
0.6=realigned the laser on the crane and changed the bulldozer wheels, this should be the last update before the contest ends

Controls:

Crane:
Control crane and claw w/ arrows and hit f to control the claw independently, when controlling the claw, use the slider to drop. The claw will automatically grab balls and will drop them if you fly over the bucket attached to the main body.

Bulldozer: right arrow is to accelerate, left arrow changes gear, your current gear (forward or reverse) is displayed on the main body. F toggles headlights. Top slider controls bucket angle and bottom slider controls the lift. G toggles tall mode

x-cavator: f and g can be hit in a repeating sequence to walk. The slider controls the drilling function.

Switching vehicles: hit S in the lower right of all vehichles controls to open selection screen. Note: the crane can only switch when the default controls are activated
