Interesting game, playing it I noticed some good and bad parts about it.
The good parts:
1. The game looks very good.
2. The controls are executed well.
3. The background music and the sound effect of the clock are very well thought out (the music does not cover the clock so that it is easy for the player to know to hurry when he is in a time crunch).
4. The Main menu and the UI are beautifully made.
The bad parts:
1. The game is extremely difficult (I managed to last a maximum of 40 seconds). I say this because many players might give up on the game quite quickly, so maybe a possibility to change the difficulty would help?
2. The lack of a tutorial or some explanations on the game description made me confused about what I had to do in the game (however, it's cool that you put the controls in the game description, but I had to refresh the page because I automatically restarted the game when I pressed "play" and I could no longer see the game description).
But overall it's a good game.
