This game is buggy AF. Losing to certain enemies can dump you into a debug map. Running around in certain areas can cause soft-locks. There's some audio filename encoding issue after the 2nd (mimik) boss, which I've attached a patchfix for to address. The last area apparently has a green-crystal flag they mishandled, so it is impossible to reach the final boss without changing one of the debug switches or editing the save data manually.
Anyhow, attached a save as well. It wasn't really much, frankly a scene collector.
Like most of the files from that site, I think the password is "ryuugames(dot)com" (where you replace (dot) with .)
