Humble Bundle currently has a Bundle with 8 cozy Steam games
I never played "Here Comes Niko", so I do not have any experience with that game.
But all the other games in this bundle I played already and they are all great! Humble Bundle lately had a few bundles with mediocre and bad games imho, but this bundle is honestly a very good deal if you have the money to spare.
Especially "Witchy Life Story", "Assemble with care", "Alba a wildlife adventure" and "A Short Hike" are truly amazing imho.
There are also two coupons. I think it's kind of sad they started to add coupons to bundles, but Haven Park I recommend as well. Don't know the other one.
Remember that you can buy this bundle with friends and share the keys! ╰(▔∀▔)╯
If you need help in how the sharing or Humble Bundle in general works, please leave a comment so we can explain how it's done.
There is another bundle with cozy games, this one is on Fanatical. The Link to the bundle on Fanatical
Fanatical may seem a bit suspicious, but apparently it's an official reseller of keys. At least I couldn't find anything bad about the site and I've used it in the past with no problems. Again, these are keys for Steam.
"Them's Fightin' Herds" is a fighting game with ponies drawn by Lauren Faust!
"Floppy Knights" is a turn-based strategy game with cards and a lovely protagonist and story.
"Garden Story" is an action RPG with a cute story and art.
"Kitaria Fables" is a farming game with cute art and a bit of hack&slash. The only game of that type that you can play in Coop, as far as I know (but only on the same PC).
If you only want to buy the smallest tier, I'd personally ditch Kitaria Fables because it sadly is a bit buggy and grindy at times.
If you need a 5th game I'd recommend Wall World! It's not cozy but rather stressful. :P A great game regardless.
The only one I've played from the Humble one is Alba but I agree it was a genuinely lovely game, thoroughly enjoyed it.
I don't know a whole lot about Fanatical or their business model but I've also bought Steam games from there in the past without any trouble, they seem pretty legit.
