1/5. Great concept and I would love to play this game. However, awful lag (which starts affecting hit detection), pointless upgrade decisions (you'll have so much $, that you'll just upgrade everything besides your weapon, except on the earliest level you can level your weapon) and the game takes 0 skill, it's all based on the drops that occur. If you have the best gun you can, everything upgraded and you can't kill the incoming waves because you get 0 armor and health drops...being "better" won't help. Back to the drawing board.
Level 21 wonky is easy to do if you build a couple front towers (a few as anti ghost is a good idea) and a long line at the end where you can get 1 mega tower (sniper, some boosts, and maybe a slow or a weaken) and where you can use the juggle technique for the ground forces. There's a level that explains juggling if you're not familiar with the concept.
Super fun (like hedgehog launcher, etc.). But it is odd that this one does give a dizzy feeling like you get when you play guitar hero for too long (everything seems to be pulsating).
