Cool game! Added to my collection. The only thing I would suggest is to add the preview of incoming stamps. This way I could make more informed decisions at the early stages of the game.
Thanks! The problem with a preview is that it's too analysis paralysis inducing. It really explodes the number of possibilities. You'd essentially be playing with 6 stamps instead of 3.
I do agree however that the first few stamp placements aren't the most meaningful. They're more like an extension of the setup.
