Hi,

When you run a final solution, where it checks at the end for number of instructions used and run time of the program, sometimes due to bugs in my code the runtime will take forever which means the simulation for the speed challenge part takes ages.

Is there a way to skip it/abort?

I haven't found a way, except Escape, which only really gives you the option of quitting the game or going back and waiting for the simulation.

Maybe try and change the bold part...?

Ha ha very funny ¬.¬

But in case you were serious and don't know this game, know that some trial and error is part of the game - even Carmack and Torvalds have to debug their code, and having to wait minutes before you can hit Back to make corrections really sucks, esp. if you're making experimental changes and have to wait such a long time for every minor change..

And some of the advanced challenges require very long run times as a consequence of the minimal lines of code, so there's no getting away from it!

It does seem like this game hasn't been update since launch too...

Press the stop button? Also there were a couple of patches as you can see in the changelog.

There is no stop button on that screen.
