I liked the posts on Habré about toys with real physics. I myself have been playing games for some time and I know firsthand how difficult it is to combine realism and interesting gameplay. In my opinion, modern games often spell out technology as a sacrifice to the pleasant sensations of the game itself. All the more cool to find exceptions.
One such exception for me was Splume.
It would seem that nothing special, very similar to other kazualki, but the developers managed to catch a lot of interesting, almost tactile sensations, in a simple ball and cubic design.
