Instructions are simple, use the mouse as direction to jump, press and hold the left click to charge jump power, release it to jump. You have to reach the flag. Good luck!

You must have a video card with hardware acceleration capabilities.

It could fail on Mac because of a bug on a library (lwjgl) to access OpenGL on Java. It is fixed on the latest version of this library but I have not updated the game to use that one, yet.

On http://blog.gemserk.com/games/floating-islands/latest is the current development version, for now is the same of the entry but I want to update some things on these days.

UPDATE: I have updated the lwjgl lib, so now people with Mac could play the game using the webstart link.
