User Reviews
So far, I like the game. It's challenging but not too hard and the gameplay is smooth while graphics are good for what they are. That being said, where is everything? at what point does it unlock what is locked on the home page? When do I get to see anything like the comic on your game page? Unlock and fix this and I will adjust the rating.
Pretty fun game tbh. The style is nice and kinda stands out. looks clean. Can really stuck in it for a while, trying to figure out the best way to build the squad and make things work
Progress got wiped but not my stage. Lost all my upgrades and resources. Can't progress because damage is too low.
forced ads begin after stage 8. During stages squad selections randomly lock behind ads, coin ones randomly become ad locked, reroll button randomly locks behind ads. Game itself isn't bad for a bag game.
