The first few levels are fun, but than its a little repetitive, all the way to level 10 same technique, borders first, than border of the borders and so on till you get to the center, a little work and its done. Level 15 is where I stopped and said "wtf am I doing playing a boring game like this?"
Bug in the game, as long as you have 2 separate routes after the choke point (preferably asap) you can trap a wave in a contained area, so that even level one pellets can take care of a wave 100 (assuming its not flying of course).
The game is laggy at 5 bars for me, thats about 12 mb per second -_- 12mbs and still horrible lag. please, this game is great, please please please fix it
needs mute button (if there is one needs to be easier to find). Also, playing on hard mode was no challenge whatsoever. This is more of an endurance game than anything.
