Doing this for Play Store points, but it leaves an impression of being an unfriendly and poorly designed game.

I looked up some guides, and they said Terence is strong, which made me wonder...? When I pressed the nickname section, there's account linking, but the difficulty to reach the specified stage is so high that it's hard to tell if it's even there or not. I'm wondering if I just have to proceed as my life points accumulate while searching for strategy guides...? There was a playthrough video on YouTube, but the bird they're using is different...
