Wow, never thought that throwing the Moon into black holes would be so much fun! I haven't finished the game yet but might come back to it - there's even a level editor‽ Great level of polish for a jam entry.
The level design is really neat and of course the planet orbits + twists + golf mechanics are a great concept and a well-executed one. The Roman Gods as a setting is a nice touch, and I have yet to explore the powers of Jupiter and Mars :)
I'm looking forward to diving into the source to see how you implemented this nice physics-based gameplay :)
