Game was great - support terrible Played for a considerable length of time and had paid for the no-ads upgrade amongst others. Attempted account linking several times but it never paid out the 100 cube reward - no great issue.... until following an update I was logged out and had to repeat the intro again... ok, no big deal, I'll complete that and log back in / restore purchases... nope. Support team refused to acknowledge screenshots of purchases and said nothing they could do. Avoid.

The best iv played so far, but so much going on that it becomes too much. not to mention you will level up stuff, just for it to become completely obsolete. also, no matter how much health you pump into your base, you will always get killed by two shots after about wave 30. the enemies do so much damage and you don't have any damage reduction, so you really can't reach that level of health that would be able to tank anything at all. worth a try, but I'm still looking for my forever home

let me preface this by explaining the gameplay itself is a fun mobile game. BUT! after the recent updates, I guess the developers got greedy. They added a feature that every 10 waves an advert pops up and is, in a simple word. ANNOYING! You'd think that if you get a forced ad at the very least give us something for it. I never minded clicking on ads that give you something for it but to blatantly force us to view it is bringing me closer and closer to not recommend the game.
