Scroll is active during the game

[CVarisco]

I love games like that and as a developer, I'd like to make you my congrats on your idea 🎉

I want to warn you that the scroll is active and could be annoying to the user during the game.
I attach a gif to demonstrate what happens.

I never make a video game and if you need some help I can help you with it 👍
