I submitted a request for this game a few weeks ago, I would like to know if it was rejected or not?

just join roblox speedrunning discord server to know the results, also you gotta wait at least 2 weeks for the results.

Ok

A month has passed, there is no information, so it was canceled?

it is most likely rejected, yes.

It will be very interesting to know why

we don't need a third roblox clone of phasmophobia on speedrun.com
