From making you do multiple things to the countdown decreasing in a different decrement, the twists this game introduces to the countdown mechanic are really fun!
The only complaint I have, albeit a small one, is the music. The music is a tad bit distracting though as it is a little too loud and doesn't sync up with the countdown, I found it easier to play without the music as a result. If the music maybe decreased in volume or changed to be not as obstructive as you are counting down the number in your head (maybe it changes volume once the number disappears?) it would be easier to keep track with the music turned on
That's only a small nitpick though. The assets are great and the game is pretty polished looking!
