App updates started in 2021 & is now way too easy against the even the "hard" AI. It hoards items instead of spending and focuses too much on energy, making it extremely easy to double its score. Also periodic glitches in that I'll play a card, pay for it, and it shows in my played card history, but I don't get the benefit. Also the update allows you to continue spending to increase temp and oceans, even after completely done (it did not before). In short, the update made a great app glitchy.
