Thanks for your contribution.
We've been reviewing your contribution and suggest the following to improve on upcoming tutorials.

- You use many blocks of code repeated, we suggest you put a function that will always use the same code is called.
The code repeated is this:
```
if blockchoice == 1:
    game.add_widget(block1)
    Clock.schedule_interval(block1.fall,1/60)
        for i in allblocks:
           if block1.collide_widget(i):
               block1.position[1] = 0
```
<br/>

- Your tutorial is quite short for a good tutorial.If your code didn't have code repetition the tutorial was very short. We recommend you aim for capturing at least 2-3 concepts in single tutorial.
