Do not spend money on this game!
Be very careful before you spend any money on this game. The developers were smart enough to make sure you get fully invested in the game before it becomes nothing but a cash grab. Playable and fun, yet challenging until you get to level 22. Then all of a sudden it becomes pretty much impossible to pass a level without spending gems, which you have to pay for. Also, the ads that they have you watch, which you pretty much have no choice but to do if you want to make enough money to evolve your ship , are many times 90 seconds long with a second 15 second countdown screen. That add length is unacceptable! I have never played any other game where the ads are consistently this long. And if you tried to contact support, it just leads you to a dead end. I would’ve left a much higher star rating if the developers didn’t ruin the game with their greed. Developers, do better.
