You are actually the first to comment on the obvious scaling error. We know that the elements should all have the same scaling, but when one person is building dungeons, another is pixelating the player and someone else is making the items or the background, it can be hard to get it all to work well together if you don't want the dungeon to look too big, the camera too wide or whatever. You can often only estimate the proportions better through testing and then redoing sprites would be very disappointing. Thanks for the feedback! (:
