I got the physical version of this game a while ago but I have held off playing it because of lack of time and because for some reason I can’t put down Dragons Dogma :P
But anyhow, I just got around to play it and it really is an exellent game. I don’t get the hate from people on this forum for the switch version (I have not played the game, or even seen it, on any other system so I don’t have that point of reference.
As for both the frame rate and supposed input lag the Switch version controlls and feels on spot with a classic Castlevania game (I made a thread a while back where I got a lot of flaming for stating that Castelvania games have always had controlls that suck). So far I have not gotten very far in the game and I have not experienced any crashes and I’ve played it both on the TV and handheld (prefer playing it on the TV with a pro-controller with a real D-pad)
Yeah, the Switch version really isn't that bad, it's only when you do get to play on another platform that you notice the difference. And yeah, it's a big difference, but... I still played through the whole game on Switch and thoroughly enjoyed it, although there were a few specific areas and rooms where the performance dipped hard.
I got 4 crashes, by the way. 3 of them were with the shopkeeper NPC, and 1 was with another NPC inside the castle. Basically, if you're gonna talk to an NPC, it never hurts to save first.
