Hi, here is an ebuild for the demo of Primate Plunge, a variant of xjump in which you control a monkey descending by swinging from branch to branch. This is the playable demo of level 1. It has a custom licence.
Created attachment 83203 [details] primateplunge-demo-1.1.ebuild I suggest category games-arcade.
games-arcade/primateplunge is already in portage.
I suppose that saves me from the embarrasment that it's not a demo... I jumped to conclusions from the "commercial" licence.
