Clicking Reward

Hey how you guys doing, so im making a game where you have to click alot of times and i want to make some sort of Reward x times they click

For example: if you click 1000 times you unlock a feature

How can i do this? Please help me

Have you tried anything yet? Have you tried to learn how to check whether the mouse has been clicked, for example?

Anyway, what you're asking is super basic stuff. I'd recommend doing some basic tutorials on 2D games, and then ask for specific help on a specific thing if you run into trouble.
