Extract the file and put the content in the resources folder
You can find it in "C:\Program Files (x86)\Steam\steamapps\common\The Binding of Isaac Rebirth\resources"
If not, go to steam and right click on The Binding of Isaac: Rebirth and click Properties, go to Local Files and click Browse Local Files...

1. Did you look at the "How to Download" title
2. Do you have Rebirth? this mod is only for Afterbirth
3. Maybe another mod causes it

If it is still not working i don't know what the cause is

If you find a bug or have any ideas to make this mod even greater, put it in the comments

Guppy loves this mod: NYAN CAT

- Updated the Title Menu

That's why i made this mod, the main character is Guppy
you should ask the guy who made brimcat if you can use his file for this mod!
nah, I don't think i must need that in this mod, but i can put the brimcat link in the description for people who want it
This way the mod maker of brimcat gets more downloads
ah, yea. would be cool tho. you should make the hitsounds a cat going like Meowww
I stopped updating this mod because i am busy with an other mod (which will release this day (I already told you on steam what mod)), so i probably won't make them meow because it's more complex than you think
the normal monster sound is used alot for alot of things, even things than arren't cat (Awesome video btw.)
ah, ok. i will get working on the challenges for your secret mod
I really liked it I made a video its not a good video but I made a video!
I have put your video link in the mod discription, Thank you for making that video
почему не качается
cool, but cricket is a dog. oh well its coll anyway
If you look at the item "Cricket's Head" it looks like a cat
i geuss.. dont let anybody knwo he is a dog!!!
people will know once they look at this comment xD
i was waiting for someone to make this
Love the mod, iv'e kinda always wanted to have a cat character that looks like guppy, good job.
I can see a good future for this mod
Great mod dude, keep up the amazing work! The only thing I would change, is possibly changing the color of the 'wings'(The things to the left and right of the 'GUPPY' text(on the first screenshot(or the title screen))). I would change this, because the blue 'GUPPY' text, and the red wings are contradicting colors. They generally don't go well together.. Possibly make the wings gray(because generally, grey compliments all other colors), or blue.
Regardless, amazing mod!
Thank you , I will change the wings when i go home
You said grey and gray. Hmmmmm.
Both 'gray' and 'grey' have the same meaning.
I know, just confused why you used both. Sorry for the massive delay, been very inactive.
