This game used to be great until the developers got too greedy, impossible to get good tech, developers only focus on end game with extremely strong enemies. Forcing you too buy coins to stay up with the currnt tech, and if you want to upgrade your ships to rank 5 youre grinding for months and months and until then a new ship has already come out and your old ones are already useless. The only way this game progresses is with higher numbers, sad, dont download. All other reviews are from when the game was still great.
Save your time.
