I would say deserved but the port feels lacklustre so not deserved. Honestly, it was expected. Castlevania games are usually seen as Nintendo Classics. With the exception of Rondo of Blood, Symphony of the Night and Lords of Shadow all the popular Castlevania games were on Nintendo consoles. It doesn't help that Nintendo fans are huge fans of Metroid which what Bloodstained also plays like. Also Bloodstained: Curse of the Moon sold like 56% on Switch despite there being like 6 platforms. This result should not come to a shock to anybody honestly.
Anyway, I got this game over the PC version because portability is king for 2D games such as this. Performance issues be dammed. I rather play anywhere over better performance.
