BIG THANKS TO ALLOC!!!
This is ONI level1:Syndicate warehouse edited level.
First, BACKUP your EnvWarehouse folder and Level 0.dat, Level1.dat, Level1.raw. IT IS NECESSARY!!! After this, just put my files on their right places and play. You have to start with warehouse cutscene.
This is English language Oni for PC version.
Have fun.

------ Converted to an AEI2 package by s10k 2017-08-19
I love this mod so I converted it to AEI2 package.
Notes:
Play this mod without any other mods installed or with as fewer as possible to maintain the original desired gameplay as possible!

The level 0 that this package is using is the "Warehouse Mod Minus The Warehouse" available here: http://geyser.oni2.net/ONK/warehouse/GlobalHacks/level0_Enhanced.rar.

Unfortunally I got an error while extracting original level0 to oni files with onisplit:
Oni Split Error:
-export "C:/Users/home/Desktop/warehouse mod/extracted/level0_Final/" "C:/Users/home/Desktop/warehouse mod/level0_Final.dat"
System.ArgumentOutOfRangeException: N?mero n?o negativo necess?rio.

em System.IO.BinaryWriter.Write(Byte[] buffer, Int32 index, Int32 count)

em Oni.InstanceFileWriter.WriteBinaryParts(BinaryWriter writer, String filePath)

em Oni.Exporter.ExportFiles(IEnumerable`1 sourceFilePaths)
em Oni.Program.Unpack(String[] args)
em Oni.Program.Execute(String[] args)
em Oni.Program.Main(String[] args)

It says non negative number is necessary. So I had to use "Warehouse Mod Minus The Warehouse" which didn't gave any error extracting via onisplit.
You can still play the original level0 (which has some Konoko moves locked and others enhanced), using the following file:
