Slidraw

Draw a sled that can get you through the course - collect every star in a course to win!

You can only draw in the designated area.
Hit the play button (or press space) to start / stop the physics simulation.

Gadgets like the thruster or hydraulics can be activated during the physics simulation with their key (small red letter) - the activation key can also be changed by pressing any key while having the gadget selected.
Parts can be rotated using the left and right arrow keys ("a" and "d" do technically work as well, but set the activation key for gadgets).

And theres always a "skip level" button somewhere.
