How could I forget Amertis, HandsFree! It was a fantastic game, much better than a lot on regular sale!
My link is not for Amertis, but a smaller free game in the same French forum where the Coliby group was constituted. The game is called Absurdus and I liked it an awful lot!
@ GrayFuss, I dind't know that you are reluctant towards free games... but if you decided to give Amertis a try it's much longer than Absurdus, with some hard puzzles and there is an English version HERE
