A decent time waster. But one of the best things about he game is trying to predict just when you will hit the very obvious paywall. Like when a planet boss suddenly has over twice as much HP as the previous one. The game could use some optimization, since it slows to a crawl on older phones. This is also one of those games where you shouldn't bother jumping through hoops completing tasks on the Offer Wall to get extra blue gems. Because you won't get those gems anyway. No matter how many you complete, you get nothing. Also, don't spend much (either real money or in game currency) on getting the drone ships. They are virtually useless in the boss battles since they spend over 2/3 of the time hugging the sides of the playfield, where they hit almost nothing, and never the boss. It is actually pretty obnoxious how they programmed that into their AI. Clearly NOT just a random thing. There is also no real explanation of why things happen. Like how suddenly I lost 4 TP on my ship. No idea why. While it grandfathed in my higher number of turrets, when I made the mistake of turning one off to see which one it was, I could not add it back since it put me over my new limit.

Great game to kill time. Simple controls, pretty easy to get upgrades and couldn't beat getting it on sale. Fun game so far

After update: increased cost (TP) of turrets... Increased reward pieces for a few battles... More then halves after that. What the hell? Please fix that. Especially if you upgrade reward increase. You could improve communication about the rewards that could be expected (and effects of the upgrades). So upgrading feels good at start. Later on, the incremental upgrades to the damage of the turrets are small and feel insignificant. The new visual effects of firing turdets after upgrades is good.
