While playing the events I have noticed that the player in front of me seems to jump 50 or more instantaneously. I could understand the jump if it was one of the purchasable amounts. Since it's less than 200 which is the smallest purchasable amount it seems to be engineered to make it impossible to catch up and win one of the top prizes. One at a time I'm catching up and then all the sudden 70 catches is added to the person in front of me. Instead of one at a time like I do. Makes it seem rigg.

Fun time waster, ads are by choice. Recent update actually made it better. But it just takes forever to get anywhere. The more you play the more you need to play to advance. Edit: it's been 1 year since I wrote that review and then uninstalled it. And I couldn't remember why I did. Everything was great. Then I started the frozen side and remembered how slow and tedious the game becomes. It's like the frozen side was written by a different person than the warm side. Uninstalling, again.

Recently, I got the winter area base upgrade, and I am now running into a delivery worker bug. They just randomly teleport back to the base, and if they collected anything from you, it gets deleted. It is annoying if you've spent time on a particular enemy and they collect it just for the loot to be deleted... Would appreciate it if you could find the cause of them getting randomly reset.
