Here's my recommendations for #indiexmas. Great games I played last year.
And one of the great things about indie games is their developers are reachable. So I'm going to include the twitter handles of at least one developer for each game.
And has it been a while since you've played Desktop Dungeons? Technically will be a game of 2013, but why not check out what they've done lately - I recommend starting with a fresh save, otherwise things might be weird, and you might need to re-learn some stuff anyway. Desktop Dungeons is my "Oh boy, I've got 20 minutes to myself, I can play a round of this!" game. Danny Day aka @dislekcia; Marc Luck aka @aequitasZA; and Rodain Joubert aka @RodainJoubert.
#indiexmas was Alex Amsel's idea. Happy holidays, y'all.
