This should end up like SIE, getting a XBLA version. Having only 11 zones is a bit of a concern though. OTOH, having 2 branches in each stage like G.Darius could mean 8 possible endings. The magazine image at the below link says something about Hisayoshi Ogura (OGR)- hopefully he's involved in this.
A zone select map is shown in the article, where you play Zones A & B first and then choose your routes after clearing B.
I don't doubt that this will be better than the short and shallow (licensed- thank goodness Taito isn't to blame) Darius R on GBA.
