This is a highly engaging hidden-object game featuring numerous mini-games and tasks.
The game was developed by a team of three to four people, but the team composition changed several times, so the total number of developers was roughly twice as many. In addition, marketers, documentation creators, and a project manager also contributed… I can’t provide all the details, especially since I’ve forgotten much of it.
The game was developed under Linux using Code::Blocks. The target platforms were Windows and macOS. The engine was a heavily modified HGE, primarily to support Linux and macOS. Here, the SDL library and its companions — SDL_sound, SDL_image — proved very useful.
The game was released around 2010. As far as I know, it is still available on various publishers’ websites.
