1. It's not bad at all, just didn't know if it was intended.
2. Haven't seen it again.
3. I don't hate it, but can imagine other people might. It is quite interesting to have rich and poor spawns, plus tension of not knowing whether there will be a runaway AI or not.
Someone who's expecting to be able to win every game via skill could be frustrated. But the games are short enough so it's easy to get back in. If someone has the expectation of something like Slay the Spire (you can have bad luck and it's not expected to be able to win every game), it works.
That having been said, it would be nice to have win percentage in the stats, or at least total games played. (I use pets rescued as a proxy for total games played)
