Built a small browser palette guessing game — looking for feedback

I’m experimenting with a lightweight browser game around color memory and visual guessing.

The flow is simple: the player sees a cartoon-inspired color palette, then uses HSB sliders to recreate it as closely as possible. I built it as a small SEO + game experiment rather than a SaaS: fast loading, no account required, and intended to be playable in a short break.

I’m looking for feedback on three things:

1. Is the core guessing loop clear enough in the first 10 seconds?
2. Does the HSB slider interaction feel intuitive, or should I explain hue/saturation/brightness better?
3. For an indie SEO/game experiment, what would you improve first: onboarding, scoring feedback, or shareability?

Thanks — practical UX/game-loop feedback is especially helpful.
