Same here. In MoonDebriefState.js, the marked line errored out, because departedLocation was null.

     var departedLocation = LunarFeatures.locationForBase (baseDeparted);
 >   var deltaX = departedLocation[0] - _base.loc_x;  <
     var deltaY = departedLocation[1] - _base.loc_y;
     _distanceTraveled = Math.floor (Math.sqrt ((deltaX * deltaX) + (deltaY * deltaY)));

I should have just fixed this if you refresh.

There is a value I expect to find in LOCAL STORAGE that is null when you first try play the game — I was not allowing for that.

I should have know to blow away local storage when testing. Since I have been developing it, of course, at some point that value was added to my local storage and I was free to write all manner of bugs that assume it is there.

Works!

Another way to handle this is to count every landing outside a pad a crash landing.

The Moon is not that harsh a mistress.

I do allow you to land anywhere — if your fuel is below some threshold I put up an alert allowing you to be rescued.

I seem to have gotten the rescue message even though I landed at a base. In the following screenshot I've landed at Maginus and it can be seen in the scope that I'm on the pad. Chrome 100.0 on Kubuntu 20.04.

Works great! Please make this (a paid) game on iPad!
