EDIT: Never mind, I think it should show you holding it... lol
That's not as easy as it seems
I'ma make a little icon in the corner to show which tool you have equipped and what it can do.
The next version has already come a long way! I've updated the graphic, Now I'm adding in puzzles. If you complete them you unlock brand new lands with a huge variety of things... I'll leave it at that XD
