Unausgewogen
Die Grafik ist gut, die ersten Level sind auch gut spielbar. Aber schnell merkt man eine große Unausgewogenheit in dem Spiel. Die Türme bringen kaum etwas, sind teuer in der Aufrüstung und werden schnell von den Gegnern abgeschossen, statt dessen muss man mit den Helden extrem viel arbeiten und das hat wenig mit Taktik zu tun. Neue Turmarten muss man kaufen, wobei man das Geld besser in der Aufrüstung brauchen könnte. Alles in allem ganz nett, aber die Unausgewogenheit nimmt einem ganz schnell den Spaß weiter spielen zu wollen.
Tower Defense thats pretty good
As a TD game, its pretty good. There is a decent variation of maps and it requires active strategy to pass certain levels. Forced ads for certain things, but they are short not those 60 second ones. Only gripe is at some point you'll need to get better ships or towers to progress, but the IAPs are pretty pricy, spending $30+ on any game for not even the full set of unlocks is pretty ridiculous.
Ok

Very fun game
I like the game play. Very addicting game to play.
Broken game
Good game , after few levels it stuck and doesn’t work
Good game - awful pricing structure
Good TD game - graphics and mechanics are spot on. The level difficulty (always hardest to get right) is OK - sometimes way too easy, sometimes too hard, but just balanced enough to make it good to play. Lots of effort and skill from the developer and a few tweaks would make it perfect. The prices in the store are ridiculous - as somebody who spent a decent amount on each of the Kingdom Rush iterations (£20?) to buy hero’s and some gold I always look to support the eco-system with some cash but these guys have no idea how to hook payments from a player. ‘Sale’ packs of £44.99? £95.99? Jog on boys! I know developers rely on whales to make a game pay but surely nobody is coughing up at these levels? It seems you either spend £1.99 with them or your entire food budget for 2 weeks.

Game hay.
Broken
I love this game you can’t play now. I was at level 45 and thought oh I’ll uninstall and that will get rid of this stuck ad, nope. Now I’ve lost all progress and still can’t play.
Great to start but….
I really like this game a lot but it seems like once you get to around level 35 is when you gotta start spending $$$ or quit. The star requirement starts getting ridiculous and you have to almost be perfect with 3 stars in each hardness in every level to keep advancing. I’m not dropping a ton of money to keep advancing so I’ll be cutting back until something changes. I don’t mind spending a few bucks here and there but almost nothing in this game is just a few bucks.
Worth a try
If you like tower defense games, I would say it’s definitely worthwhile to check this game out. Good graphics, pretty good sound, and a lot of action!
Pop up
There’s a pop up that can’t be closed. Breaks the game.
Leider kein Update
Ansich cooles tower defence, allerdings nicht für das Iphone geupdatet. Funktionen sind teilweise nicht sichtbar, beim drag and drop der Towers minimiert sich die App. Schade. App wieder gelöscht.
It’s fun
I was able to get through the first few levels without having to spend money. A lot going on in this game.
It was fine until they got greedy
Game was better than your average defense game until they added a ad pop up for one of their other games. No way to get past the ad. The box won’t close and the link it wants you to use won’t work either. Swing and a miss.
Crashes
Game crashes all the time and has a ad that pops up that you can’t get out of even after restarting the game great game just buggy

Ads broke the game
Ads are great, aren’t they. A good portion of the gameplay is spent watching ads. Which is doable except when the game is no longer playable. Here’s a quick horror story. A game ad came on right before the main menu and it’s stuck, front and center. I can’t close it or tap anywhere to make it go away. I tried uninstalling, resetting, and punching myself on the face in frustration, but nothing works. It just sits there, haunting me, reminding me of the fun I used to have when I was kicking tower defense rear end. It’s truly a fun game with good graphics but ads said nope, not today! Or ever. My motto is if it ain’t broke, don’t fix it. Well this game is very broken in dire need of fixin.
Decent game
Fun game, but difficulty and resources are set so that around levels 18 and 19 you effectively need to start spending money to win. Not a big deal, but important to know before you get invested.
So far, so great!
Hope the difficulty graduates smoothly, without sudden extremes!
Could be 5 stars
Fun game but after level 2 an ad popped up and you can’t close it even after closing the game completely. I hope they fix it.
Ow…
…ticks all my boxes. Loved this game. One of the best TD’s I’ve played in a long, long time. It just feels so slick and polished. Great addition to my TD collection…although once you’ve cleared level 5 from level 6 as usual they’ve ramped up the difficulty to such an extent you cannot cope with the onslaught unless you pay the extortionate IAP’s they offer. Such a shame cos it’s really a very good game but the massive difference between level 5 and 6 is shameful. They build your hopes up, you leave a rave review and you try the next level and 🤯 so frustrating when they crank up difficulty too much.
Cool game
I like this game!
Broken game unplayable
You can play a few rounds but it gets all stuck on a developers add about their other games. The little pop up recommending this developers other games cannot ever be dismissed. Tap, and smack it on the X r even “Play Game” button all you want but it never moves and makes this game totally unplayable. So don’t spend a dime or you’ll get stuck.
Game
It’s alright the only bad thing is all the ads they need to come out with some more games
Третьесортный шлак
Содрали механику с первопроходцев жанра, дисбаланс от слова совсем. Играть можно одной башней. И конечно смотрим рекламу всегда и везде
TD
Enjoy the game very much but like most games I hate how they force you to go to tutorial but other than that so far no issues and I plan to keep playing.
