Some text editors (e.g. vim) save temporary files in the same directory as the file being edited. So, if you edit an airline xxx.json, the assembler may found .xxx.json.swp in the assets/airlines dir, include it in the package and fail:

[13:37:30] SyntaxError: Unexpected token b in JSON at position 0
    at Object.parse (native)
    at fs.readdirSync.forEach (/home/grand/openscope/to

What is the current behavior?

When you are on top of an NPC and want to trade/shop/bank with them. The popup screen will not popup UNTIL you move and FINISH its progress.

**If the current behavior is a bug, please provide

It would be nice to have a crosshair instead of a cursor while aiming for the shot.

Hello, lets add a section where the player can set the game difficulty level before he/she starts play.

Select Difficulty:
