This is the Demo for a logic I will use in the newer game coming soon: Chase 4.0. An object moves and triggers the clone squares I somehow managed to make possible without to much math. Your mouse works in this one too as a demo.
Thanks to all those who make grid effects, I took inspiration to make a simpler version. With this I will lean back over to the original style of Chase 1.0 and include new effects while keeping on topic. Just realized this can be used to track your mouse on the page, meaning it can tell if you are about to hit the pause button or start button. I may make a demo about this later.
