So I downloaded the game and it opened normally, but when you have to hold down the right button to continue, it doesn't work, not even the left button to exit, I wanted to know if this problem was just for me.

This is very strange. The game was tested on different devices and everything worked just fine.
What input device did you use? Keyboard or gamepad? Can you test both?
Actually, it should work with both, but this might help figure out the problem.
Also try switching between windows using Alt+Tab, maybe the game doesn't have focus after launch for some reason.
