This game was developed with Flash/ActionScript and later ported to HTML5/Dart. The similarity between ActionScript and Dart made it surprisingly easy to convert the as3-files to dart-files. The StageXL library provided the Display List, the Sound classes as well as the Resource class as a replacement for the embedded resources in the SWF file. Because of the similar languages and the compatible API the task was accomplished in only 6 hours. The most surprising outcome was the performance of the game in HTML5 - the game runs at smooth 60fps even on hardware where the Flash plugin is unable to deliver good performance.
