Wasn't expecting much before trying, but I feel like this game is not bad after played about 2 hours. At least its gameplay itself is something different than ordinal F2P games. Ads and timers are annoying indeed but still acceptable.
So I am level 38 and have played the game a lot and all for free as I don't purchase IAP in 99.9% of games in case of certain special cases. The game is far too criticised for IAP and ads yet I barely recive any ads and can close them instantly anyway so they are no bother to me. Also IAP is basically just to skip waiting so there's absolutely no need. The game would have been better being paid and that's it but the way I see it I just saved £2.99 or whatever it would have been and still get to play a lot! So I can't play continuously for a long time but I can play a while go do seeing else and come back and I prefer a lot of games to be like that as it's on a mobile anyway generally I play in short bursts. It's a fun game and free just give it a go : )
I'm surprised it never got more attention - one of my favorite 'tower defense' games - love the graphics, gameplay, etc. It's one of those games I keep installed on all my devices...
