I really enjoyed this game! I love the theme, and it fits well with the game jam. I ran into some bugs, though I don't blame you as I also made a similar game using Godot's GraphEdit node. The robot would sometimes get stuck when dashing into a wall, and the game would freeze, forcing me to refresh the page. One time, the mouse wheel wouldn't zoom in or out in the graph, so I used the buttons instead. I'm on Firefox if that helps. The game may be a bit difficult for non-programmers, so it might need more play-testing. I liked the look of the game, and liked the robot-kangaroo. I think it's a great concept that can be expanded upon. Great job!
