5 stars: Game is great, f2p friendly, I'm looking forward to more updates, mayb something like reincarnation where you loose nearly everything but gain great rewards and power for starting again.
4 stars: Played it for a while. Works well from my experience. However it does have a common glitch where it does not do offline rewards so I just have at the same stage until it actually works. Apart from that, simple fun game.
4 stars: Fun game so far. Graphics are good, concept seems well thought out enough to keep me engaged for a while. I like that the weapons have an upgrade limit.
3 stars: I like the game. It's a slower pace ehoch is good as I hate rushing too fast but perhaps a little too slow... offline progression fails over 50% of the time. If offline progression is fixed, easily 4 star game or higher.
3 stars: The progression was slow. After rebirth, the weapons level also being reset to the certain degree. Need google play achievements.
