How do I create these?
The simple script is, when an object is touched by a player, the player falls over
The possibly complex script is that I need a box to appear on the side of the screen, which says "Return to stage 1) and when you click it, it resets your score, or sets it to one.
Thanks in advance.

I have 0 experience with scripts. I need a WAY more in depth answer.
Look for tutorials and learn the basics. Then try to do this.
