Mod showcase from What was my friend https://youtu.be/m22J3ajdjIQ

(Outdated) Made on version 0.4.0

For Mod of the week, for now the updates for the next version are here, but i am buzy fixing something for it (fixed it :D)

Updates about the next update.

This has been Moved to the Discord!


The mod at V0.20 needs Undertale Foods By Marshmello7119 to operate, so this acts an warning when V0.20 comes out.


(This is Invalid as i tried it but it ended pretty badly so compatibility is not possible at the moment)

The link to it https://mcreator.net/modification/96719/undertale-foods


This mod is Early Stages of alpha and may contain many Bugs and Glitches, if you perhaps find then you can report it true the comments or discord server.



Q:when will level Fun Have level generation?

A:Prob never as i have tried with V0.13 and it just doesn't work so i need an more complicated generation system for it


Q:How many levels do you want to add

A:It depends on allot of factors but im thinking i wanna do at least the base 9 levels so level 0 - 9


Q:How can i suggest stuff?

A:At the moment there's no real way of doing it but i will fix that at one point. But for now use the reply section


Q:Will you make an fabric version?

A:No because i did forge so that its compatible with most good shader mods like optifine


Q:How accurate is it to the backrooms?

A:I don't know what to say really but i would say level 0 is pretty accurate from what i heard form my friends


Q:Will there be custom sounds/music?

A:Well i have talked to my friend (who knows an decent amount of music/ambiance creation) and were right now looking into it but i cant guarantee it


Q:Is the mod scary?

A:What do you think >:)


Q:Will the mod be server compatible?

A:Im not sure if its possible but i can try.


Q:Can i make Extra Addition Mods for this mod?

  1. A:You can if you want but i don't recommend it in this early state of the mod, as i am not sure what to add everytime so if you maybe make an level like level -0 for example then maybe in the future i make an level called level -0. My point is that if you make an additions mod there's an chance that it becomes useless in the next update.


Q:Can i add this to my modpack?

A:you can add it to an modpack, do you have to give credit ofc.


Q:Will the mod get texture updates?

A:Yes every now on and then i will do an texture overhaul.

this is to get feedback and maybe some help...

normal backrooms = 👍
d.a.r.k rooms = 😱
loot = 😎
this mod is 👍😎

so umm Little Halloween Update for the rest im just buzy with V0.13.5

the mod is really cool, but the textures are kinda lacking in my opinion. I swear I've seen the same texture in 5 different mods
