Yokai Idle
YokaiIdle is a lightweight idle RPG built to fit around real life. It progresses while you're offline, with skills, classes, Yokai companions, and combat.
Main game: Yokaiidle, if anyone wants to play directly. Roadmap.
Some images (Yokai, items, etc.) are still being created and may be missing for a while as development continues. (I decided to use AI placeholders while we catch up)
Combat will update (Currently it's full auto) once I am done with some other minor updates.
This project is developed solo. All feedback, comments, and ratings are genuinely appreciated.
There’s also an in-game feedback form if you’d rather use that instead of commenting here.

Sorry to anyone been playing, due to that fact it's free I am not paying the server costs :D

Sorry again... ive moved to a free server so it wont break again.
Hey! Thanks for checking out Onigashima Idle and leaving a rating. (I don't want to post your name without asking, but I also cannot reply to ratings directly..)
I saw your note about combat not working — I haven’t been able to reproduce it on desktop yet, so I’d love to know what you experienced.
If you’re up for it, could you let me know:
- Desktop or mobile?
- Browser?
- What happened when combat failed?
Really appreciate you giving it a try 🙏
Combat doesn't work for me either, I'm on desktop/browser and my character is unable to attack.
Here's everything I did:
Started as a guest -> chose the ninja class -> followed the tutorial -> got to the combat section of the tutorial and after spending a few minutes searching for an attack button, I finally realized my character was just completely unable to fight back due to a bug or whatever -> tried refreshing the page, restarting my browser, re-equipping my weapon and yokai and creating an account but nothing worked
Okay I just figured it out as I was typing this: you can't use the stone axe as a weapon, equipping it makes your character unable to attack and I'm guessing you can't use any other tool for combat either (Chopping a sakura tree also takes longer with the stone axe: stone axe: 3.15s, No tool: 3s)
That makes total sense now! I'll change the non-combat weapons to have some attack potential so that you can at least try to do combat with them. I think the tutorial needs tweaking, too. In my mind, you would have the spear at that point; maybe I forgot to change it.
Thank you 🙇🙇🙇
