The game is fun but gets difficult, REALLY fast. You go from blasting away 10+ alien ships within 3 seconds to taking up to 3 seconds or more to destroy just 1. Meanwhile, there are 15 or so swooping down towards you while shooting away at the same time. Upgrades don't do much to help. The cost of upgrades go up with each purchase, meaning you run out of currency to use, very fast. Even then, they are weak upgrades.

Beginnings are fun, but later it's unplayable for free users. Too many ads, repetitive, unjust, unfair. At some point, progressing is limited to paying customers, upgrading your ships above certain levels is available only after buying crystals or cards. You don't receive enough of them during normal game. Ads can break the sound in the game, and pause your music. Free users are limited to 20 games at a time. Then you need to wait for energy to replenish.

I am obsessed with the gameplay. It's very entertaining. However, ever since I started playing almost 2 years ago the devs have been changing the things a player is forced to do just so the company can attempt to make more and more money off of players. It has gotten to a point now that a person has a limited number of playable points just to do anything in the game (even playing the main campaign levels) without paying real money for more just to keep playing. It's not worth it anymore deleted!
