From the creator of Passage comes another similarly themed game - Gravitation.
Taking on from the lessons learned in Passage, Jason Roher has created a game which, while on the surface is similar, hides some devious machinations.
Taking the form of a more game-like design, Gravitation still holds messages similar to its predecessor - so obviously try downloading it before reading on, so as to keep you own opinion of it separate.
Apparently the role of the main character is of the father. The daughter wants to play, and when the father allows it, she glows with happiness. However the father has other things on his mind. The stars and the furnace apparently represent creativity. While travelling upwards - which can only be done while on fire - you'll come across stars. Harvesting these then burning them will fuel your creativity (points).
However while doing so, your "daughter" will grow increasingly lonely. Deciding what to do - and what is ultimately more important is the key to this game. No matter what you do, it ends the same, when the time is up. Deciding how to spend the time you're given is important - what is more important is how you decide to use time after you finish playing.
