decent game heres somethings I find hinder it a bit
1.) the lay out of the map and the areas where you can set up towers is both bad and limited meaning if you don't set up everything right your screwed right from the get go
2.)the fact that level three upgrades needing to be constantly unlocked in each level is both ridiculous and very bad especially if you burn up a lot of funds to upgrade the towers then run into "upgrade not available cause you didn't unlock it for the uptinth time"
3.) agreeing with others the music is annoying so thanks for the mute button
