Build from Source

You first need to get hold of Jame (https://github.com/nickthecoder/jame), which handles the low level graphics, sound and user input.

Itchy uses the gradle build tool. Here's some useful targets :

gradle compile
gradle extractNatives 
gradle installApp

The "extractNatives" target extracts the dll/so files from jame's jar files.

Play

Linux :

./launch

Windows :

Run the "launch.vbs" file
