I bought this game on Steam, which incidentally I continue buying from since GOG decided it was ok to brush us off. It's a unique Castlevania mixing serious themes along with more casual ones, and it entertaining and skill based, well worth the money. It says a lot that GOG has continued to exclude games from this developer from its marketplace, given this game has absolutely no contentious content.
Incidentally, this "GOG wishlist" redesign was an Arasaka level decision to hide previous comments from petitions like Devotion's, nobody asked for it and it serves its purpose, an excuse to hide old criticism. I can look past Devotion, I feel I have boycotted GOG enough years now for its decision, but I refuse to come back when "many gamers" want games like Nine Sols and GOG still refuses to host them because of a foreign country's attempts at censorship. Steam is better than GOG's faux virtue signalling.
