That was an experience. I attempted to delicately balance the energy and couldn't get past the 1st stage. Like the other commenter said, I then "embraced the chaos" and that was quite fun. I eventually even made it to stage 2!! :D Great job!
One note - a couple of times when I died, the "retry/quit" buttons wouldn't work. It wasn't consistent, so possibly just some weird Godot state issue or browser thing. Just in case you continue with it, something to be aware of.
