No clue, it's available on itch.io if you want a DRM Free version tho.

According to this Shmups topic[shmups.system11.org], there is no DRM-free version. itch.io contains Steam key only.

I guess they want to be forgotten. Whatever...

Same reason Dariusburst, Jets'N'Guns and all CAVE games never got released on GOG.

GOG curators said SHMUPs are too niche and refused to sell them on GOG.

Go and ask Rake in Grass (the Jets'N'Guns developers) if you don't believe me.

And yet we got R-Type Final. We also have the Raiden games.

After reading this I asked over at GOG discussions to confirm or deny what was discussed here.

I did not link the thread or mention the specific thread.
