Calming and minimalist experience, well done. Sadly i couldn't see my score at the end
Huh... Did you see the "R to restart" text? I made extra sure that, even if my leaderboard went offline, the player could still see their own score as a percentage at the top of the screen.
Then this is weird i can't see anything, maybe it's online version
Can you try pressing the "T" key a few seconds after the clock has stopped? That key toggles the leaderboard on and off.
