One Curious Nightfall is a short but very interesting game that's coupled with one awesome soundtrack. The game is beautiful and definitely worth checking out and experiencing for yourself. In the game, there are several rooms that you need to explore, with each room holding a surprise of its own. Gameplay is quite simple and the graphics is 2D but it's still pretty amazing. It's a bit short so don't expect to get too attached with the game since it might be over even before you start getting a feel for it.
