I've been working on a game that I call Heaven Town, it's not done yet, but I thought of showcasing it here.
The game uses Farseer Physics and Project Mercury.
Video showing some features here:
The goal of the game is to build, really, a town in heaven. You build small islands, puts buildings on them and connects them using rope bridges. There is also resources spread all over the world (the blue and yellow stuff in the video). Blue is wood,
yellow is gold and gray is stone (not in the video). In the video you may notice some small, black figures flying all over the world (well, not literary flying, but it seems as if). They are the inhabitants of the town :P
