I have seen this a while ago on TfGames already and at least the version there was basically just the same as EP:Backrooms, just with less content.
To be fair I haven't played much, as EP:Backrooms already got boring after a few hours and so I already did not have much fun with this one from the beginning.
I could understand, if different people made their own games with this engine or something, but this game seems to be made by the same person as Backrooms.
I don't see why someone would work on multiple games that are so similar, without first finishing one of them, especially since Backrooms already changed during its versions.
I thought about the developer trying to create multiple games without much effort, to gain more attention and probably money, but for a scam like this, the similarity between the games is just too obvious.
I just don't get it at all.
Well anyway, since the first game was not able to convince me, especially in the later versions, and everything was filled with Patreon ads,I guess I just will refrain into looking into any of the games for a few years, until something significantly changed.
