This is currently my favorite game. Yes, it does seem like I say that every other day, but that's what happens when you have a ton of super great games available to you. Space Tap is actually a phenomenal game, that will keep you entertained for a while. Space Tap is about one thing and one thing only: Lead ships into the docks, watch them unload their cargo and direct them off the screen.
The only problem is there comes a point in time when there are a lot of ships and if any of them crash into each other, it's game over.
