I tried a run on my phone, and I wasn't logged in on itch on my phone. So it started a brand new run, as a guest account. And yes, it didn't load the game. So, what I did is, I check marked "Desktop site", and the game loaded normally. But the window was too small for precise clicking. But it was an easy fix, I just rotated the screen to the horizontal view. It wasn't a proper full screen, but it was good enough. :D
