I agree with a lot of your points and thank you for taking the time to play my little proof of concept. I didn't have time to make a feature to sell pets after you own them or to rename them. Those were supposed to be features you could unlock along with an upgrade to make the pets assignments stick but the whole upgrade shop had to be cut. I probably should have taken away the confirm buttons they were some UI that made sense at one point but I think I streamlined their usefulness away. I want to overhaul the UI majorly if I come back to this.
Only thing I don't agree with honestly is the like and hate being the same. I purposefully left it in as a possibility to give you a chance for a pet that's neutral when it comes to like and dislike. It's pretty much how pokemon handles neutral natures, but I should have probably swapped it to say "None" in the case of them being the same.
And don't feel bad about the criticism I appreciate it. Data about what works and what didn't is super appreciated and I don't think you were being harsh.
