Fun until you get to the satellites. The "hard" ones are just unfun. They are always faster than your alien, no matter how many upgrades you get, and just fly off the map where it's impossible to reach them. Then the game starts goading you into making micro transactions to make your alien stronger, like ooh maybe if you buy this you'll be able to catch them! I gave up on the last set. Too annoying, not progressing at all since they just scale speed and health and will boost away off the map.

Catching speed has been reduced since the new update, previously I could run past low & medium level enemies and collect very fast. Now I have to stop, even for the basic enemy. Other than that, this game is 5 stars all day long, fun gameplay, and decent progression if you don't mind watching a few ads (ads are not forced) which is nice. All events full into 2 Brackets, straight collecting or collecting & upgrading event building, the latter sucks.

It appears that the most recent update slowed down and reduced the power of my character significantly. I used to be able to attack about 10 enemies at once, but now it's down to 2. It feels like all the grinding I did for months was wasted. For what it's worth, the events are unbelievably repetitive with poor rewards and an obvious pay-to-win structure setup. It's too bad because this was a lot of fun at first and for a while.
