Cool concept. Had a lot of fun playing it. It's like a colony sim where you have to babysit all of your colonists and make them build effigies in your honor. The graphics are awesome as well as sound design. Obstructing the players view into horizon will benefit to player's immersion and it would not feel like you are building something on a floating terrain in the middle of a skybox :) You should probably add a more practice oriented tutorial on few examples so that you don't overwhelm the player with the things he has to do throughout the level.
