Congrats, it's very well designed and feels great! I really like the graphics and the overall look'n'feel. The game logic is quite well done too; like often in such games I tend to be a bit frustrated when I shoot in the middle of two balls and it gets sucked in at the wrong position :p
The Sims background is not exactly a libre asset, but well.. ;)
I hope you'll continue to improve the game a bit after the jam, it's a very good example of what can be achieved with Godot in a couple of weeks.
