Stage 44

Unsure what it is about this stage but no matter what I do it’s impossible to beat. Respectfully, I’m not putting money into the game and personally, it feels as though I have reached a paywall. Otherwise, the game is great.

Melhor Tower Defese EVER!!!

Um dos se não o melhor jogo no estilo de defesa de torre! Underdark dar a possibilidade de personalização e progressão no jogo que uma forma absurda! Amo o jogo! Comprei a versão premium no Android e compro de novo agora!!!

Great fun!

Love this game. It is great fun. Just wish it could be played offline. Constant internet connection for every little action is frustrating.

Would be perfect if available offline.

the game is amazing for passing time but find it annoying that you’re *required* to be online in order to play. I understand it’s required for the monetization elements but I still think it’s strange, as it would be perfect for a long car ride or plane trip, given you could play in that situation.
