I am a big fan of Super Auto Pets, so I am always excited to try games similar to that.
I am happy your game has an offline mode now.
Pic below is the best team I had.
The game crashed, and it does not work anymore, I do not know what happened, but I had fun when it worked.
Everything is super tiny, and the first time I leveled up, all shop went blank.
If there is a way to "freeze" shop, then I was not able to find out how to do it.
