Look at first post to read about using it.
File links are the same.
shift + e results in exception:
you cannot save a map twice with the same name, overwriting doesnt work
here my first try to quickly make something annoying/hard =D

Hello, thanks for bug tracking and sorry for delay.
Bug was fixed. And added requested feature.
If you already saved/loaded this level, you may save it with same name by pressing Ctrl+S. Without saving request. But be carefull. It will rewrite old file.
Note: Don’t use “.json” in saving/loading level. Extension will be added automaticly.
Possible, but it does feel frustrating. I suggest implementing an easy way to see if you’re good to land or not, and perhaps a meter for how close you are to that goal. Currently I can’t really tell anything, other than looking how fast the ship is moving over my screen.
When making my approach to land, I tend to watch the angle of entry in the data feed (upper-left corner), as well as speed indicators – just like in a real moon lander!
I loved it
You could always make a map generator.
Just put the goal on the opposite side of the player, and distort the land in-between to reasonable lengths.
Thanks. But in near future I want to redesign application architecture and back it conceptual integrity.
