The last weekend I played the game NightSky
(by Nifflas). I think everyone knows about this game, it is quite popular, and really awesome! I really recommend it.
In this 2D physics platform game, you control a sphere trough really beautiful enviroments. The physics engine is really awesome, I was quite impressed. Again, I suggest playing it (at least the demo). Maybe it's a bit too short for the $10 it cost, but I think it was worth it!
Has anyone else played this game? :)
