I'm breaking the Game.

Yep. I'm breaking your game. I'm in the last Level, on Elite Difficulty. What round am I on at the time of typing this? ROUND 713. I'm playing until I can get it to stop working. Already I've made it glitch, Lag, then crash by round 550 or round 660 (Odd, right? I'm using an iPhone 4S too so it works!) I'm gonna break your counter, or keep going until your game can't generate anymore Big Bosses (Most I've dealt with was 3) and Devastators (The reason I've bought the Anti-Tank barricades and half the map is covered with them)! Anyway; Bug issues I've found that weren't related to my test. YOUR DEVASTATORS SKELETON GUYS CAN GO THROUGH WALLS!! IVE LOST AT LEAST 9 GAMES BECAUSE THEY SLIP THROUGH MY NATURAL BARRIERS!! Fix it pleeeease!!! Oh! And the Ads! They're not coming up. I can't earn my SA$ without the Ads. Please fix it so they don't have to load so slowly!! I've got Zombies to kill, I can't keep waiting for a Dr. Pepper commercial to crash my game!! (Yeah, they do that.) Anyway, amazing game; annoying bugs, BACK TO KILLING!!

Great, but cash grabs more than CoD

I find the game quite entertaining. The basic tower types keep it simple and the maps have a linear increase in difficulty. The only thing that grinds my gears is that to play on any difficulty other that "normal", the zombies become so invincible that I find myself struggling without the help of a "booster"(cheats you have to pay for) in some way. Also, I don't understand why restarting a map doesn't keep pre-purchased boosters. If it applies to that game and I just restarted it (not died and hit "try again"), why not maintain the booster? There isn't a multiplayer so the only one I am taking enjoyment away is myself. Also, if I buy boosters on a map, why not discount it for every purchase? I am tired of saving up money just to waste it on trying to earn more money on a higher difficulty, when the booster barely seems to help. I love Ninja Kiwi and all that they do, but there are major problems to address here.

Impossibility standards?

Okay, I'm seriously not alright with the fact that I would have to spend twenty real life dollars, so that I can have something I could spend say I don't know, ten dollars on a similar game, and get about 60X the enjoyment out of it. You guys definitely got some of the difficulties switched up, or you guys just really need to learn how to make a fair game. You did fine with bloons. Heck, bloons was easy. But this game is IMPOSSIBLE. there is no possible way to win on normal, without being a hardcore elitist gamer, and there is no way in gods fiery hell, that anyone is going to win your nightmare difficulty, without paying some serious real life cash, to win one round.

Another thing, you should let us upload our character out of the SAS: Zombie Assault 3 game, and let us set that person down, upgrades and everything. It would promote both of your games, and make some of us gamers, feel a nostalgic feeling of having our old persona from SAS 3 to fight with us again. It would be awesome, but I don't think you guys even read these reviews anyways, so I guess I might as well not post this. But hell. On the slight chance that you do, please consider what I've said. And please. Please, make an easier difficulty, and allow us to build ourselves up, instead of completely decimate us from the very beginning.

Thank you for making games Ninja Kiwi you make some of us gamers smile.
