The game is cool, and so is the concept, though there are a couple of caveats.
Since it was made in just four days, I won't be too critical.
1.
It’s not entirely clear when to press, but it’s still good.
2.
To me, it doesn't quite fit the theme, as I don't see a countdown anywhere. If you're referring to clicking those light-colored circles, that’s a depleting counter, not a countdown (though that doesn't matter too much—let's be realistic).
Otherwise, it's great.
4 out of 5.
