What is Familiars.io?

  • A monster catcher game!
  • Massively-multiplayer online! (Your friends can join you!)
  • A relaxed setting where you can collect silly familiars in a mysterious world!
  • An optional competitive PVP scene with a very small learning curve!
  • A place where you can greet other players with a "howdy!"
  • A world where the lives of familiars are precious - if their HP reaches 0, they're gone forever...!
  • Extremely easy to get started, especially if you've already played games like Pokemon!
  • Entirely free! (And free of ads!)
  • Playable in desktop and mobile browsers! (Really, the mobile experience is quite smooth!)

I hope you enjoy it!

(This game is still being actively added to! My twitter is the best place to hear about updates!)

How do you save? Or does it auto-save?

Just a normal picture with Cobby. Nothing wrong at all. Ignore the threesome in the corner.

Oh god I can't stop them.

I understand what it is now! It's a player fighting an enemy.

pretty interesting, a bit too unforgiving for me maybe due to my lack of pokemon experience but i don't really feel like wanting to get a stronger teams because of the risks it involves. maybe slightly more common potions? idk tho, its great as of now, just not much to do until you update it again and do some advertisement to increase population

Also, not sure of a bug or just a feature that makes the game even scarier but poison carries over from fight to fight with seemingly no way to remove it

"A relaxed setting"

Jokes on you permanent monster death makes it immensely stressful looool (kidding. a bit. I do get very attached lol)

This games pretty cool even for me who kinda just plays by myself even in online games, love the critters!

Good game, but there's never any players.

I found this oil can item and what am i supposed to do with it?

can you make it so that familiars dont be gone forever make it so when there hp is 0 level down them by 3 levels and if they get to lvl 0 they are gone fovever

1. Train A LVL 1 Familiar To LVL 15

2. Train One Type Of Familiar To LVL 15

3. Get All Kinds And Types Of Familiars

4. Beat A LVL 15 Familiar With A Whole Team Of Either LVL 1 LVL 2 LVL 3 LVL 4 LVL 5 Familiars

A good game but it lacks a lot too keep people Interested for a long period of time. So far I've found any monster having or being a dark type to be very powerful. In my opinion the strongest monster is wispy that thing just won't die to any physical attacking monster In the entire game.

I really like the game, the pixel art, the little animations, and to be an indie game that has good characters and logic, I will probably keep playing.
*also what is Patch's colours?

Episode 34: Works in Progress


It was fun to hear about which things stood out to you! Thanks for making this :)

Hey, can I support you in some way? You really deserve it.

:) I do have a patreon here: https://www.patreon.com/clayloam?fan_landing=true

This game is incredible! I love the cute creatures and the addictive simple and really well done game design (the speedy levelling is lovely)! Would be nice if there were little trinkets to collect or something at the end of the underground sections or something. Great to hear you are still working on it, and keep it up, you have something awesome here

i love trhis game, its so cute

This game is super fun! Love the aesthetic, hearkens back to the good old pixel pokemon days. I look forward to seeing what else you add.

I had a 30 minute fight between my Wispy and a sensor

This game is an absolute delight! <3 my cobby

Just massacred a carbon and a button familia in pvp, feeling good.

Game just crashed, had a maxed out cobby and maxed out patch, felling sad

should auto-save, try refreshing the page!

Just put in another hour of my time into this, great game, so good, hope to see some environment intractables added to the game and also winning items from winning a match

Noooo! Carbon!!!!

I cried when my seeker died :(

Looks fun and I just started playing

Very interesting io game concept and pretty fun, although I would have liked to know that familiars die permanently before my beloved snake died ):

Oh no!!! I completely forgot to add that aspect to the description... may they rest in peace

Love the UI, the smaller viewport constrains in a way that only adds to the wonder of exploration and to the nostalgia of playing GameBoy.


I'm excited for both the game and the dev behind the game. Both are amazing!

Super fun, super easy to pick up game. None can defeat my Cobby's magnified corn gun :)

Awesome game! The familiars are cute and the UI really is top notch.
Also  a great way to find back that sweet feeling of discovery and adventure I had playing Pokemon Red as a  kid!

very cute, would recommend playing :D
