Beacon
Beacon is a short, fifteen minute freeware game that lets you control a spaceman that has crashed and landed in some unknown space rock. The game might be short and features simple 2D graphics but there's something that's enjoyable and fun in playing this game.
This was created for the Ludum Dare 48 game, where developers who participated had to create a game in a 48 hour deadline. Despite the game's simplicity, it features a wonderful and atmospheric mood. There's also plenty of depth in the game that makes you wish it was a little longer.
Since the game was initially released, it has been polished, making it a little more faster and better than the first version. Give the game a go.
