It's true - I did create these accounts with the intention of playing the game on mobile for a bit to see what was working well and what wasn't, improve the mobile UI, and learn more about other ways to improve the new player experience (e.g. tutorial.)
My intention was to cover up my multis so that I could at least play for a few weeks and see how it went, but I did a poor job with my first once and then I thought I patched it so I wouldn't show up on the same unique ID for the second account, but again there must have been a bug there.
Nothing particularly nefarious, this is something I've done over the years and IMO has led to a lot of quality of life improvements in the game. In fact, one of the most common criticisms I've gotten is that because I don't play the game I tend to make bad decisions in developing it.
Other than my main multi account though, Kastor, there's really nothing remarkable to see here. I just went through the tutorial and objectives twice on my phone in the app version of the game.
