Block Heroes is a first-person exploration/construction game that looks like Minecraft, but instead of building forts, you build giant controllable airships and robots. There are no limits in Block Heroes but your imagination and how hot you're willing your laptop to get.
Very Promising, I was able to build some functioning planes and cars, even both in one. The buildingprocess was hard sometimes, but its easy for the programmer to lower the difficulty (i suppose :) ). If this Project goes on like this, I´d pay more for it than for Minecraft.
