>this game was set to release in March of 1993. Know what else released at around that time? SPLATTERHOUSE 3, in Japan on the 19th

I don't think having another game of the same franchise released at the same time is something that would prevent release, on the contrary, I think it's something that would help release it. When it came to late Famicom releases publishers precisely liked to release other games in the same franchise at the same time on other platforms in order to cut advertising cost, as they would advertise several games on the same page (because few were crazy enough to spend advertising cost on just a Famicom game at that point) and also hope that coverage of one game helps spread knowledge of the other game(s) released at the same time and spread the franchise's visibility more.

Pic related is an example, Konami's Batman Returns should have released on Famicom in Dec 92 at the same time as the SFC Batman Returns released, advertising shows both at the same time; but the FC version ended up being cancelled too. Konami was especially found of doing this, Tiny Toons Adventures 2 on FC was also advertised alongside 16-bit games in the franchise etc but they weren't the only ones doing this, it was a widespread marketing tactic for late Famicom releases.
