Hey! Thank you for trying my game! I suppose you're talking about the transporter belts at the start of the game. I'll try and make it clearer in following updates, but the instructions given by text are intentionally misleading. There are other paths !
I will do a quick update ASAP to the web version to add indications. In the meantime, check the controls by pressing Escape and selecting "Settings"! it might give you help to interact with buttons for example
