In these days I’m playing mostly casual puzzle games, because I don’t want to invest time into the usually long playing sessions required for adventure games.
The one that I have enjoyed a lot and that I have just finished is “Hook”:
It’s a game that requires observation and some “circuit logic”. The goal is to identify the removable pieces on the screen and to route the “remove command” so that it reaches only the pieces that can be removed. It’s a very short game (only 50 levels) but the later levels can be challenging and finishing it it’s a rewarding experience. Also, it doesn’t cost much.
A perfect brain-teaser.
