Moved translate to every tick (to enable gravity, -10 to z). Change down to set x value. Add ground for character to move on. Also changed project to regular z instead of normalized z. Do not use normalized z for 3d project. Also sort based on camera distance for 3d layer (for 3d project).
You don't need the ground, but for me it feels better to me to have a ground and some fake gravity for a kinematic character controller. You can delete the ground in my example and the 'D' movement still works (but it will be falling due to the fake gravity.)

(This is the physics library embedded in this addon, a subset of the many features are exposed to C3 right now.)
