What UI are you talking about exactly? The battle UI, the overworld corner UI, or the pause menu UIs? Or all of them?
The platforming is supposed to be difficult, the game is meant to be a challenging game. I'm totally fine with people struggling and dying a few times in the beginning, but if it becomes like completely excessive then that's a problem. So far most people I've seen play through it have died 1-5 times ish, which to me is completely within the realm of what I'm shooting for. Do you think it's significantly harder than that, or do you just not really like difficult platforming?
