Just another game based on ads and spending money. There's nothing premium about that. I don't blame developers for wanting to make money, but I sure miss the days of just buying a game once and enjoying it. I'm not looking for a never ending drain on my bank account just to keep playing, and with the length of the ads these days, I can't justify the waste of time. The time I spent playing yesterday and today was worth the ten cents I paid upfront for the game, but that's about it.

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.

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.
