It's a fun, visually good game for the first 10 levels. It gets very difficult approaching level 20. Ads are long, sometimes multiple ads in one. It forces you to watch ads to get the specific skills/abilities that you have upgraded to use (random choices after leveling/elites). Been stuck for a while now around level 20, even after purchasing a starter pack and some gems. If it weren't for the high price to remove ads and the very difficult paywall to progress, it'd be close to 5 stars.

great game, but... excellent game if you treat it like an idle game. if you dont want to spend a lot of money to get through lvls quickly, this is not the game. This game is very expensive. I did buy the "pay to get rid of ads packages." Dont even bother if you dont want to spend a dime. I have notice, for some odd reason, they made the game harder. Was able to beat 10 lvls below my max lvl with ease and didn't have to really pay attention. Now its 50/50. Seems very fishy to me.

thought it was a great game, but then it turned out to be nothing but "buy this pack, buy that pack". "Oh, and btw, you can only play for a short time... UNLESS YOU PAY TO GET A PACK OF ENERGY, SO THAT YOU CAN PLAY MORE!". But, even if you get more energy, you will stagnate unless you buy the pack you need to upgrade since the mats you need habe a drop rate of 0.0001%
