This is relay cool! But just add this to your stuff
When drag stops
> Set X pos to Round X pos
> Set Y pos to Round Y pos
end
So there will be grid snapping you can also change the slowdown to 50 to enhance friciton
I have a idea like add a block with like repeat (0) like I make it repeat(50) and the green thing falls and goes 50pixels up and falls and repeats again and again until stop
