Apologies for the large overall download size, but this is trying to be a real game not just an engine like a lot of other open source "games" out there.
I've split it so that you can download the source code, check it compiles ok, then download & extract the data to actually play the game.
Thanks to Antonio Strijdom for getting the mac version up and running!

If you can help out with graphics please contact me, since I can't create decent looking stuff. Below are screenshots of some of my attempts. And no, the main character is NOT supposed to be a stick figure :)

Level 1 - Shipwreck Salvage
Level 1 - Shipwreck Salvage
Level 2 - Lava Planet

These graphics were mostly done in Blender and pasted together onto the background bitmaps using Gimp.
If you feel up to the task of helping out with the rest of the graphics (and possibly redoing these ones) please email me : paulrahme@yahoo.com
