Great job with your game. It is a very solid and complete game. I definitely played more than I had planned. I thought the upgrade system and general gameplay to be very excellent and well thought out. There was lots of variety in the upgrades. I like that you gave more than one type of target to shoot like the bomb and bonus points. Awesome, fun and very well polished game. Keep up the good work!
Edit: I also needed to add that I appreciate that the RMB toggles on an auto-clicker. My forearm was starting to get sore.
