How to use:
First, you need a goal.
For this tutorial, let's say the goal is "hitting a target"
Start one meter ,from the Target and for every time you hit it, press the "Success" button
Every time you miss, press the "Fail" button
If you come really close, press the "Close" button
Every time the level increases, move back a meter
Every time it decreases, move one meter closer.
This can also be applied to other tasks, but a target was the easiest to explain.
Have fun!
