A very old Danmakufu game, released in 2006 which is the same year Concealed the Conclusion came out! This same developer would go on to make Toho Feveron.
Quite a tough game... and this is only Original mode too. I am pretty sure Nightmare mode is impossible to clear (even the developer admits this). I could challenge the Extra stage after stage 3 and the Phantasmagoria stage after stage 6, but that puts me on the Nightmare route for the rest of the game which is something I do not want to deal with.
Also, I appreciate all the PC98 references.
