the game itself is fantastic. 5 stars. However I have an extreme issue with their recent updates. they recently tailored their shop against play pass members. they did this by removing everything we could 'purchase' from the store. I can use my gems to buy things in the store, but I can't buy any new gems or bundles. edit: 2 month later. still same issue for play pass. and now we have to kill with a lvl 1 hero for event. wondering if it's somehow easier for other players. also no buy for them.

It's a good game overall. Initial layouts keep levels from being repetitive, so it gives your brain more to think about what to place where. My only real negative is that the game sometimes crashes and makes me replay a level from Wave 1; if I have to do that when I was at Wave 7 or higher, it's disheartening.

Game is fun, and I paid for the play pass to remove ads and other things. Now I am a bit put out because the ad tickets are not included in the Play Pass... They were when I first started but then they removed them. Game is still fun but that really was a sneaky thing to do. I have brought this up to Google and they agree... Very sneaky. I would not play this unless you have the Play Pass, or money to burn. I give three stars for the sneaky. If it goes back then I will give 5.
