Derp: Use the manual time out to your advantage, if you are getting a very slow combo, use it and get more proxy mines. Also put buzz saws. They're overkill.
So let me get this straight, we're playing a game where you control a turnip and you're running around for no reason with epic music. Your turnip is able to shoot about 360 bullets per minute (that's a lot of bullets O_o) so you can knock off some one-eyed bats to obtain points and a combo which some randomly messed up rainbow appears when you do. There are TV' screen the size of your turnip which if you touch, gives you a seizure(ish)screen so you can fire epic l@z0r!?!? dots? @W3$0ME
This game is awesome and i dont usually say that to other games. 5/5
For some tips on the last level, move your city to the bottom left corner, this makes it easier as your on higher ground.After that, just start developing
