Awsome
I got to level 82 before i finnaly died, because i forgot to let my base get back to full health before going to the next level. The game is great though. but after you have all of your weapons fully upgraded, its more like shooting a big rapid fire shotgun with a random assortment of bullets in each shell, instead of a bunch of differnt weapons. my solution to this, give each weapon differnt properties other than just speed and damage. for instance have the cannon weapons not stop when they hit an enemy. having the barrel of the weapon also change when you upgrade it would be cool. but all in all this is a very good game, however it is plauged by the same thing that plagues every other defense game, after youve gotten all of the upgrades, and theres no new enemy types to look forward to, it gets a bit borring.
