NightSky review. Classic Game Room presents a CGRundertow review of NightSky, a downloadable game from Nicalis on the eShop for the Nintendo 3DS. Originally released for the PC, NightSky has been brought to the 3DS by the Cave Story and VVVVV developer Nicalis. NightSky is a physics based puzzle/platformer. It's kind of like if you combined Marble Madness with something like Limbo or the iOS game Contre Jour. You control a small glass sphere, and you have to get through the screens.
