I definitely recommend Baba Is You and FEZ as well. Similarly to FEZ there is a mobile game Monument Valley (and Monument Valley 2) which I adore. It’s spendier in $/time, but I find is highly worth it.
Bastion isn’t a 2D game, but I’d like to recommend it while I’m at it, it’s play is perhaps close enough, and it’s stunning.
I have a pair of cheap UV protection sunsleeves that I’ve cut to just cover my wrists-forearms that I wet with a spray bottle when it’s crazy hot. Works incredibly well.
