Great graphics and sound effects and music! The badges are easy to get (Easy Points) and it is fairly easy until the last few levels where it gets relatively hard. I did 17/18 levels without buying stuff. I noticed I failed 18 4 times so I spent 11k on extra waves and LOTS OF NUKES! I bought so much My computer got a lag spike.... Great game. Very fun! I got all the badges too in about an hour. Also I named the named the octopus Steve. He's my room mate now.
