Definitively an original idea for sure, i never thought i'd see pool mixed with bullet hell but hey that's game jam magic right here :p
When you say the game is hard well you're not joking, i had to use the skip menu cause it's really hard to defend the 8 ball and i wouldn't have been able to see much of the game without it.
Still, solid entry i really like the epic music, the very hd looking assets and the devil guy on the title screen \m/ è _ é
Great job to you and your artists you guys made a cool game :)
