i've got this simple code working as i want, but the performance sucks getting only 30fps on pc and even less on android.
i presume the mouse position checks against the box_collection every frame slows this down.
i could spawn a "square" at he mouse position. but i want to bring a sqaure to life, rather than spawning.
