ReleasioTale is Supahsta's upcomming mod of Undertale. He dosen't really know the release date. It maybe will be release after Undertale's fandom ends.
Its going to be a graphics hack, and the gameplay and stuff are going to be unchanged, so no Toad Physics or anything like that. There may also be text changes. It won't have Toad Snow.
It will take place in the ReleasioTale Universe.
Shadow Mario has also mentioned that he might make ReleasioTale.
It has probably been cancelled, since Supahsta has a problem with TranslaTale.
