I played it now and then for some days, not more than a few hours total I think. Why not playing a good game longer than five minutes? ^^

Well, I was completely lost, so I looked at the source code to find the mini map. Then I went to the position of the warp. I think the warpdestiny should be the position of the other warp in the map. As it is right now, you get teleported to the position of the first warp, so you don't move at all. This way you can't reach the exit or do I have to do something else? Btw, to everyone who loses track in the map source code: Press Ctrl+F and type in "0". Then all 0 will be visible and you can find your way. ;) It would be funny to have something like a summary. So you can look up what route you took. Maybe after reaching the exit. To do this, you could create an image and draw a colored line every time you move. And then, when it is needed, you display that image.

Update the scenario and check the "publish source code" box bottom left to make it downloadable. You can also make a world with buttons to choose the map and create the map then.

Oh and because I wrote it here, too. Storing only didn't work because of Java 8. Same thing with the bug which made it necessary to reset before playing. Should be all good now :)
