Polar Coordinates in Photoshop.

Someone could make a program for a polygon editor. And could be better if sprites had flags like PICO-8 for the collision function one because you might have multiple sprites that should have collision and would otherwise be repetitive.

I'd still like to see a small remake of LSD Dream on TIC-80 or PICO-8. I don't know why
but alt-J reverse engineered LSD Dream for JavaScript and there's LSD Revamped made in Unity. It's a mesmerizing game.

Evaluation? Zooming and panning would be good also.

Why should you use y-position? Can't it be automatically, so you don't have to add numbers everytime?
