Ah ok, I finished the game since then. So I saw in one of the readme that the server A, B and X need to be rubbed. I thought that that is a hint so I need to smash all the three Pico8 butons at once (Button A, B and X, which are X,C,V in my keyboard), So I did it several times while the screen goes purple with an error message: "Out of memory" which I thought that all part of the game. I didn't realized that one button saves a checkpoint and that's while I heard the *beep* sound and everytime it's occupy a little more from the RAM getting it full.
