Our tool is an orb. You throw it around to teleport (or onto higher platforms to replace a jump), you throw it at enemies to damage them, you set it on fire to burn things, you make it glow to have a "torch" in the dark. You can even see the world from the orb's perspective to spy around corners. (We've got a dozen other ideas that would work well with these existing mechanics, but you gotta limit your scope in a game jam somewhere :D.) We built a little dungeon-escape adventure around these mechanics, but we think they could be turned into a really interesting VR metroidvania. :)
Your golf game looks neat, I'll check it out over the weekend! (I just recently finished Golf Story, which definitely convinced me that a golf club is very good candidate for "One Tool, Many Uses" :D.)
Edit: overlooked the "share your screenshot" part.
