It was cool, but...
What you should've done was, cancel out the items that were weaker than the one you bought. Also, you should've told us if the game was endless, or is there a last level in it, and if there was a last level, you could add a boss to it with it's hp bar on top of the screen. Other than that, this is a great way to pass time.
Really fun and addicting
Gets SUPER repetative though...
Pretty cool
Pretty decent game.
By the way, it's a base not a fort, ya damn two-year-old.
Fine the way it is
I like it. It was fun just trying to get the upgrades. I wish the game had medals though.
fun
Most fun I've had with boxes since Metal Gear Solid.
I agree with another reviewer, boss' at lvl's 5, 10, etc would have been nice.
enjoyed it all the way up to lv 28
