Wow, Well done on this game and congrats on your first jam! It's amazing how simple but fun two pendulums can be, and how chaotic as well ahah
Just a few things if you want to continue developing the game after:
1- maybe I'm dumb but took me some time to understand you could actualy move the position of the pendulums before starting
2- would be nice some particle effects when using the lil boost, to know where is the force being done
3- Limit the lil boost, I spammed it so much that the pendulum went bye bye ahah pretty funny but probably not the behavior you want
