EDITED: The issues below had been well addressed. 5 stars back! PREV REVIEW: The game before this update, was great. I loved it very much. Post update, the alien suddenly unable to attack more than two targets at any given time. Previously it's so easy to grab around 10+. It made gameplay much slower than it previously is. I believe it is a glitch so do have a look at it. Otherwise, do let me know what possibly is wrong from my end, though I doubt it as I hadn't tinkered any settings etc.

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.
