This is a very clever concept and core mechanic, it feels very clean and smoothly implemented. I enjoyed shooting across the board and billiard-ball-smokin the jellies off into oblivion. Simple yet effective tight primary gameplay loop. What was the original theme of the mini jam?
Also I enjoyed the humor of the intro story. I can imagine this game and theme expanded out into an epic odyssey to bring about the age of a somewhat decent breakfast…
If you ever do expand upon this idea I think you will find a lot of mileage can be achieved by iterating across the primary mechanic. Either through adding interactions (new enemy types, mechanics etc) or through taking that mechanic on a sight seeing journey (castle crashers style) with expansion of your humorous premise via immersive storytelling, thematic stages and interesting boss encounters.
Great work, continue to grow and challenge yourself.
