So the switch version dropped tonight. I forgot about it and thought "Well I'll turn it on just to see what it's like." That was an hour ago. The game is damn good and I would go into detail but there is really no need. Did you like Castlevania 3? Well that's what it is only with modern improvements. It no longer takes 5 seconds to switch characters, the sub weapon has it's own button, stairs are easier and quicker to navigate and monsters can be much larger. Obviously you can save as well.
I thought this might have been a throw away title just to keep interest in the "real" game coming next year, but it seems to be damn good in it's own right.
It's only 10 bucks so you might want to give it a shot.
