Mocha o'Lait

Somewhere in my top five games of all time, at present - a list that also includes NieR:Automata and Undertale. The less I say about it, the better - go in as blind as you can, and bear in mind that once you've beaten this game, you probably won't have a strong reason to go back to it. (A consequence of its nature as a puzzle game!) Good music, clever puzzles, good story; well worth a play, but again, make sure you know as little about it as you can.
