Two Player in Keen 6 and Ninja difficulty: Here second player helps the first to get to higher places.

Talking about difficulty, now there are six. Don't worry, the original ones remain unchanged. The other ones make the game more challenging. So be prepared!

Keen 9 runs, but some enemies have flaws. We are working on it.

Elite difficulty. More enemies, different colors and stronger. The second player decided to hide in the tree and now reads a book. Do you see him? :)

Keen 4: Hi Elder!


Keen 4: Thank you for rescuing!


Keen 4: Pyramides fully working!


Keen 4: Even the switches trigger what they are meant to trigger


Keen 4: Keen can stand on moving objects in Keen 4. Seems simple, but it's very difficult to program


Keen 1: New Mouse Driven Menus


Keen 1: Controls menu has been split like in Keen Galaxy. Better for the mapping as there is a lot you can map now.


Game Launcher: Not quite like the mockup but already very polished


Keen 4: Those menus also work now with the mouse


Keen 1: New video Engine. It is much faster and you can now stretch the window to any size. Also the resolution handling is much better


Keen 1: No more TGA files. The routine has been removed. Most of the graphics are now embedded. The rising points got a new design and are natively drawn. This will be interesting for mods which have other points.


Keen 1: Message can also be closed by the mouse. Nothing special, but the framework does it for you.
