Do you expect mobile games (in portrait mode) to be playable with one hand?

I'm working on a game that I had finished before but the controls were unintuitive. Specifically, I thought the controls were great but my friends told me it was garbage and they couldn't figure out how they worked.

I understand where they are coming from. If you look at the screen of the game, your instincts tell you how things should work but that isn't how I programmed it.

Now I have 2 options:

1. "Original" - my unintuitive darling which works perfect once you understand it
2. "New" - intuitive but cannot be played effectively with one hand

I'm going to have to go with the New version unfortunately, but I am curious about mobile play with one hand.

Hello! I think it depends on gameplay process. Let's consider chess or checkers, I expect one hand playing for for turn based games or games with low dynamic.
