Nice start – the typing area is visually focused, and the main game layout did not produce horizontal scrolling in my desktop/mobile pass.
The clearest improvement is first-load weight. The results section eagerly downloads all eight 2048×2048 animal images even though they sit roughly 580-5,975 px below the fold; several took 6-13 seconds to finish here. loading="lazy" plus smaller WebP/AVIF thumbnails and srcset/sizes should help materially.
I also found no non-empty heading and several visible icon-only buttons without an accessible name (aria-label or visible text), so keyboard/screen-reader users cannot identify those controls. At a 390 px viewport, the lower ad link was clipped past the right edge. The core desktop typing surface itself felt clear.
