Not sure if this is a bug, but the screen is blinking so much I can't look at it for more than a few seconds, and you can only see the squares for a single frame before they're gone. Controls doesn't seem to do anything either on my end.
If I try to emulate the early days of video games, this was really like a pong-style game, but I couldn't make it play with the mouse wheel like the first pong machine. The first game is only up so that the player can go up and down and down to launch it you just have to reach the egg at the end it changes to a casio style era followed by the commodre 64 that's why the screen emulates the screen of the machines of those times
I'm sorry if I hurt your eyesight and I appreciate the comment, greetings!
