Haha, maybe you just have a sixth sense… or some kind of luck ability for unlocking 3D early :)
Just to check: when you mentioned ideal hand positioning, were you referring to the Dash and Jump controls?
Yea it felt a little awkward with dash and jump and 2 all in one column.
My sixth sense was accidentally enabling 2D mode (revealing the text) while trying to double jump and move to the right at the same time, then I assumed that 3D would work too.
Oh, I completely forgot that WASD can also move the character.
