re: What is your favorite cozy game?

I have hundreds and hundreds and hundreds of hours in Slay the Spire.

Once it came out on iOS it became a mainstay on my home screen. I'll put it down for a few weeks or a month and forget about it, then pick it up on a whim and find myself playing constantly for a few more weeks. Even if card based stuff is off putting (it is to me, largely), this is to me, the perfect cozy rogue-lite game where every run is different, the challenge continues to grow as you get better, and you can play at your pace. Seriously, if you have avoided the game up to this point, I can't recommend it enough.
