This game was made in under 48 hours for Ludum Dare. Ludum Dare is a game jam featuring an 48h competition and a 72h jam. In the 48h event, a single person has to make a full game including all assets such as graphics and sounds. In the 72h event, pre-made assets are allowed and one can work in teams.

The topic of Ludum Dare #38 was "A Small World".

Sounds have been generated with bfxr during the Compo, others been recorded and modified with Audacity. Music has been initially generated with Autotracker and processed with mplayer. Graphics were drawn with the built-in editor of Scratch and occasionally further edited with Corel Photo Paint.

Packaging was done with Junebeetles .sb2 to swf converter and the swfzip tool.

The game, including all its assets are provided as open source under CC-BY-SA-3.0
This game was made with Scratch, a versatile graphical programming language developed by the Lifelong Kindergarten Group at the MIT Media Lab. See
