Ok, easy check:
open the game folder, if you see MonoBleedingEdge or just Mono, then its a mono game, if there is neither, check the (Gamename)_Data If there is IL2CPP folder there its a IL2CPP game.
if you are the one and only guy who managed to get the new version 1.40, you might need IL2CPP version. if not, then simply:
have the 1.39 game which has bepinex with uncensor mod. (from here) the folder should have BepInEx.
since the game uses older Mono, you should download: UnityExplorer.BepInEx5.Mono.zip from the Github
then open the zip, open the plugins folder, and extract the folder called "sinai-dev-UnityExplorer" into (gamefolder)\Bepinex\Plugins
and lo and behold, you have it.
be aware that while I tried replicating the enemies, they (at least for me, I may be doing it wrong) have limited intelligence, and if you spawn too many, they float away. replicated friends did not get added to the list of friends (but i may try to replicate catgirl, let her be done in, and then re-capture, might prove funny if nothing else)
That is because you usually spawn them inside the first one, spawn them, hit them until they split or until down, and then let them figure out what they are doing, they usually go about their way if you let them respawn and leave the area for a while, although they seem less agressive as opposed to normal ones.
