Thanks for all of your comments, I'm just having fun, I may make another one (G&W game) I'm currently making my own version of Tapper, the arcade game with some graphics that I created back in 2009 for the iPhone 3GS and never used. I'm creating it with Godot game engine. The tick was just an escalating tempo thing to create tension, like the thump, thump in Space Invaders that gradually gets faster and adds to the tension over time etc.
