This project has obviously worked.But today when I checked it to check how it was coded,it did not run apparently because some custom block does not recognize the ticks variable anymore.
Any updates causing variables or variable scopes to behave differently?
I don't know why it's stopped working but it still works in v9 if you still want to just run it

When I've wanted to find out what commit causes something to change, I use my own fork of Snap! and use the git bisect command
But you have to be keen 
Everything works,though apparently high time warps make it super laggy.Maybe it was like this,but I recall the warp to next apsis function actually worked without too much lag.
