I almost didn't notice that this evolution happened it was so subtle! In fact I almost made a small update post saying there was no change.
Other than that minor change I noticed I've been losing the game more often now, but I'm still having better luck with it than I did the identical Morino Tamagotchi game, so I think maybe at the beginning it starts heavily rigged in your favor and the odds progressively get worse, although I could just have wonky luck.
Also, literally as I typed it out, I realized that the game being near identical to the Morino could mean something about its mechanics, though I think for the time being I'm gonna treat it as a normal Tama unless it gets stuck on a life stage.
