4 stars: Great fun game, but has flaws. There's not enough explanations for what things are and what they do. Some things will be found out by trial and error. You may gain or lose materials you did or didn't want.
3 stars: Fun for the first while, but in later levels, it gets suspiciously difficult. Bordering the line of hacks. Bad guy twitches, suddenly I'm dead. Forcing to watch an ad to continue, spend money to continue, or quit. This could be because I'm a bad gamer boi, but the difficulty takes away from my experience.
5 stars: It's a lot of fun! The difficulty curve is gradual, and it doesn't force you to buy powerups using real money, so it's well worth the price of admission. The game is currently discounted to $0 as I'm typing this, so grab it now while it's free! It's a great thing to play while we're all quarantined.
3 stars: It's a fun game. My only complaint is the fact that this game has an energy system. So once you run out of energy the game is boring because you can't progress the campaign.
3 stars: Really fun. Reminds me of Galaga; arcade game I used to play a lot as a kid. If you want a no brain space invaders shootem up, you found it.
