I'll premise this in that I don't recall what game (or games) they were but there was definitely something I played that allowed the player to actually reposition and resize the orientation of the buttons.

I may not have been built in unity though 🤔

I think one major issue is the blue arrow for the next stage.

It ends up directly between two attack buttons and thus often unpressable.

I think the next stage arrow being near the top of the screen would be more accessible.

The button layout out is way out of my screen and sometimes I need to press harder to attack
