While the controls for Galaxy 55 are still kinda wonky, it's hard to refute the fact that the game looks like it may have potential for the future. Helmed by the good folk at Twinoid, Galaxy 55 has been described by its developers as a 'Minecraft-esque' adventure in space. When we first took a look at the game, there was very little to do. However, the developers have recently released Alpha 2 of the game and it appears as though we'll be able to customize spacecrafts and tinker with the crafting system now.
