3 stars: for the most part the game is fine however there is two issue that I have with it. First, when choosing what ammo to use there should be more information listed. For example max dps and projectile count are a two that I can think of. Second, the game doesn't always notify you when you can buy upgrades. I think it should be changed to check every upgrade and notify you when there is something purchasable and not just some upgrades.
5 stars: This game is fun! You souls try it.
4 stars: This is a fun idle game where if you want to idle, you can, but if you want interactive play, it's also there. It is very difficult to end up not being able to do something. You can always run a mission, or merge more guys, or Return. The best bit though, even though the paid version is not super cheap, it really removes all ads and gives you all the ad bonuses for free.
3 stars: I dont mind the banner ads, or the watch to earn ads, or pay for stuff...but hate when you do all that and it still automatically opens more ads. Then instead of what other games do to earn more this one you have to give more permissions. On top of this it seems the just basically reskin the same game over and over and dont care what people think.
5 stars: Never boring awesome game. There is always something to do. Timers are short and the income for all currencies in game is well designed. Progression is fast at the beginning then slows right down (which make it more rewarding for the grind)....
