I read the instructions, I feel like most people play these games, play for 10 seconds, and then leave stupid positive comments. I've learned alot from people leaving good and bad feedback for my games. The controls for this game aren't really organic, I don't like switching between the mouse and keyboard to move. I also would've liked to have seen music and sounds. I think you've got the foundation of a game here, upgrading and deciding on what to buy are always addictive elements.
