A lovely little game to unwind with!
I liked that the duck can move backwards too, it makes steering the parade feel much more forgiving. No problems with loading or playing.
I did miss some music: since your sounds are already synthesized with Web Audio, even a simple little marching tune would suit a duck parade perfectly.
One small game design note: picking up a torch feels like a collision, even though it’s a good thing. A brighter, more celebratory sound or flash would make it read as a reward.
Also, I loved reading your AI Tools section, a whole team of AIs including a Grok playtester is quite the parade in itself! 🦆🔥
