Really fun defense Tower type game. Ads are a pain and the cost to remove it is not good

I have played this game much longer than any other mobile game. I am not one to pay to advance in a game, so this game is perfect for me. There are plenty of game modes, that are all fun, to help make my defense better.

I have played this game and its predecessor for quite a while now and find it quite enjoyable, I had wanted to skip all the ads so purchased the VIP package, which makes the game simply fun without a chore. The only gripe is that the price of the VIP pass was equivalent to that of an AA game produced from a large studio, I think perhaps a more reasonably priced offer would be a VIP pass to a bundle of these devs games to offset the initial outlay, just my economically minded opinion.

Changed my review to 2 stars. I've progressed to level 20 almost without paying anything but the grind is tedious. The adds have increased and loop... the worst of it is you have a 50/50 chance that watching an add restarts the game, and you lose all progress on whatever level you were on. That killed it for me. Add that events are pay to win, and coop levels never match you with a player equal to your level or picks cards specific for that level... physical or electric or energy and so on.

Game designed to cause you either to grind or pay to advance. Many FOMO events and when you team up with someone for one mode (binary star)they are always under powered. For all the "random" draws I've consistently gotten the worst of the prizes. Progression is slow and grinding the same few things every day is boring. Weapon system and this idea for a tower defense gane is fun. The events seem pretty cool, but then again, they feel less designed to help you and more designed to make you spend $.
