Yeah, thanks! Found the name of the game at around the same time you answered me, and was able to access the actual screenshot with Web Archive. The original includes a small spaceship which is missing on the KolibriOS version.
> The creators later made Myst using the same technology
Tried to play Myst as a 10 year old, but wasn't smart enough to figure it out. Maybe Cosmic Osmo is more on my level ;) Really want to try it out this weekend, according to Wikipedia it was a pretty revolutionary game. Also never heard of Hypercards before today (the last Hypercard update was released the year I was born).
