I enjoyed this game more than I expected, and of course I also think it's worth the small price. What I like best about this game collection is that it's full of atmosphere, and packages casual games in a time bound format. In other words they are time based experiences that find their own ending regardless of winning or losing.
My understanding is that this has to do with the games being related to sound? Like, soundtracks?
Each mini game is very original not really in the core mechanics but in visual ideas and execution.
Overall, really enjoyed it.
