I can't really understand why you won't purchase any more of Amanita's games, even after all this trouble. Their games are high quality, and are very good.
Because it sucks to be blocked in the middle in a game (Botanicula). Because it sucks to loose all saves (Machinarium).
What quality are you talking about ? Gameplay and graphism, yes. Stability and reliability, no.
A bug is no entertainment. It was many years ago the last time I encountered such issues, when the computer era was totally different (Atari).
In 2014 it should not occur and at least it should be treated appropriately.
