Disallow Enter Key to start game

Hi!
Im referring to the topic “First Space Bar Click Scrolls to Bottom of Page”. I inserted your edited game-logic.min.js file and it worked well with the space bar. But now I still have the problem if people fill in my contact form (which is on the same page) and hit the Enter Key for a new line, the game starts and typing is not possible anymore.

Do you have an edited file with BOTH Space Bar & Enter Key are disallowed to start the game (thus only the Arrow Up Key will start the game).

Further question: is it maybe even possible to disallow ANY Key to start the game and insert a “play” button which the user has to push with the mouse cursor?

Thanks a lot!

All the best,
Jan
