I love this! A fun challenge, and a nice way to practice my clock reading skills haha :D
And of all the games I've tried so far, I think this by far is the most fitting game for the theme of "TIME"!!!!
Good job coming up with the idea of comparing clocks - so simple, yet very original and nicely executed! The ramping up of the difficulty and the hourglass pickups really made the game fun to keep playing :)
