TLDR: Everything that's there is great, everything that's missing is... missing.
That is to say: Love the visuals, the animations, the mood, the polish (Timer, popup) You even got the itch.io stuff managed well (gifs, title, theme on the page).
And then there is of course infinite possibility to expand on this. I think what's missing the most is music or SFX. But I know myself that it's not possible to get everything done in this short a time.
