This is a really fun physics puzzler! Accounting for the gravity pull made for some really unique solutions and I love the quality-of-life addition of showing your previous trajectory. The audio felt like a great backdrop for the heavy thinking the game asks for. I would agree with the previous comment that UI is the spot that could use the most work. For starter, using red and green is always a hazard for color blind people. I have a minor color deficiency on that spectrum so I was able to spot the difference between the bad nodes and the destination, but I did have to look longer for it than probably someone with perfect color vision would have to. A better solution would probably be to use some sort of icon so even if you can't tell the colors, you could tell them apart by the overall look. Or you could make the destination the only one with a unique look and make it a lot larger than the other dots. Making the destination really pop for its surroundings on the map I think would in general be a good idea for helping to get people straight into the action.
