For some reason, I could not put the right answer at all. It would always say that the answer is wrong and that I have to try again. My suggestion would be to put a tutorial scene at the beginning of the game and let the player know of any controls that he might need to use during the game. Hope I helped.
Here is my game if you want to consider rating it as well: https://itch.io/jam/brackeys-4/rate/723573
