Designing the main character of my game (Patreon)

Here is a short video demonstrating the work I have done so far around the character of my next game demo. It was unexpectedly difficult to render the led screen with proper filtering (antialiasing & mipmaps.) I had to use textureGrad in the GLSL shader and spent almost an entire morning with pen and paper, figuring out the formulas.

Next, I will work on allowing updating the robot's screen and - after that - focus on improving the controls. In particular, I need to limit the velocity of the robot, to prevent it from acquiring gigantic inertia and going out of control. I also want to confine the robot in the room. These tasks seem trivial, but they are not, as this is relativistic dynamics. I cannot just flip the sign of the velocity or something, this would violate the rigidity constraint, just to mention one of the problems
