I liked this one a lot.  It was a neat concept.  I think you pushed the color palette a bit, but I'm not sure if black counted as a color.  

I hit a couple bugs - one where I somehow had -1 of a resource after building a spotlight.  Another where when I was hit while placing a spotlight and then couldn't move and my character just kept sliding south-west.

Still it was a fun survival game and I liked that it had multiple resources of varying levels of value.  It felt like it had a nice balance of difficulty - not an autowin, but not impossible.  Fun game.
