Thank you for your comment! I'm aware of that problem but only noticed it later :\ At first I didn't want to give instruction for a specific key because it can be played on a Keyboard or a Controller. To fix that I'd have to build a system to detect if the player is playing on a keyboard or a controlled and send the key accordingly, but I was short in time.
I guess the 3 day deadline was really tight :p
I sent the keys here as a comment though.
