So many games have tiny text in portable mode. Paladins, rocket league and fortnite are games that spring to mind. Steamworld game maps are too small too.
I found Sonic Heroes too hard to play in handheld mode because everything was so small - was okay docked.
I played Steamworld Dig 2 through on handheld though and it didnt give me any problems that i remember tho.
