It is so simple that I can't call the tower defense, but it's still very pleasant. Monster waves roll towards your castle, and your defenders knock them down. Update to use more heroes, towers and archers, and improve the skills of the defenders and the castle itself. It is an endless loop, but it has remained fun beyond level 300, so the developers did something well. The ads are optional, they never push on your face. Recommended. I often don't play castle defense games like this, but I really like it. However, it is a simple, but accelerated concept with a few mechanical and moving parts, one thing I would like to see is the ability to activate and disable heroes spells when it comes to automatic mode. As an example, the liabilities of the white magicians are fantastic, and the spell is a good boss of the bosses when they play manually. In car, although it will be launched in Stupid Times at the beginning of giving any chance in boss fights that are easy to manual. Addicted to the tower defense game. It offers advertising videos to win coins, but it does not make you see advertisements. I have not played enough time to see if money is absolutely necessary, but from stage 10, the game is fun enough to play for free. However, there are tons of articles to spend real money, if you want to facilitate things or want to support the game monetarily. Great game. Simple but entertaining. It is not too simple, although you need a strategy and a good investment in heroes and towers. The only things that I do not like are the gold costs for the gold mine and the improvement of the front towers. The gold mine is literally a loss of money, it is too expensive for a tiny return and later it is a joke. And the towers are too much for their benefit, I stopped updating them at 600 because they were not worth it. Both things need back, please A really fun game. The ads are not intrusive and you can choose to see the 30 ads to obtain good rewards. But you can progress well without them. The game can be easy or challenging depending on the strategy present. Honestly, I would qualify these 5 stars even if the game were bad just because the ads are not forced
