So my friend stayed over last night and convinced me to play
Doki Doki Literature Club, a visual novel where you write poems to cute anime schoolgirls. I don't want to spoil anything but it's quite an incredible experience - things start out quite straightforward, but after the first hour or two the game becomes something quite different from what you'd expect. It actually reminded me a bit of the first time I played Frog Fractions, which I suppose is a bit of a spoiler in itself... anyway I highly recommend it!
