That was probably the case if you are certain you saw the + sign then.
There were a few? D: I only remember seeing one of them. That's pretty pathetic that they did that though :/ That's good, there are probably quite a few others that like you too!
I think Infinite Undiscovery is good! It's on the short side for an RPG, but it was still pretty enjoyable. The combat is kind of like hack and slash which I liked a lot and although the story wasn't the best I still found it interesting. Only thing I really don't like about it is the item crafting. Currently working on the "Compulsive" achievement (which requires getting every item) and the item crafting has gotten quite annoying since there is a good majority which are obtained only by crafting x.x
