You've gotten 44 hours out of a 10 dollar game. I think anyone would start to get tired of a game like this after putting 44 hours into it. I really don't see the issue here. I mean back in my day we played games for fun...that was the factor that brought me back.
I totally imported because I've been pretty excited to play this game for a while. It's the closest thing to a 'new 2d castlevania' (which are among my favorite games ever) that has come out in a long time.
