I think I have found an accessible pet game for the watch
I found an app the other day called Mu watch pet where you take care of an adorable blob and level up and give your blob tasks and it has rpg elements like resource management and strategy and leveling. I find this playable. The iOs app is only showing stats, though they are a little unordered. On the watch, however, everything is labeled except for the button to do things that is unlabeled, but once you press that you can see all of the options. I haven¨'t had the chance to play with it much but am trying to reach level two.
