Fun game and cool concept, I like the idea of incorporating the clock as part of the actual game. Also a nice fun art style!
Only complaint I have is that the timer bonus can spawn in the red zone and won't respawn like the stars do, which essentially puts you at the mercy of the RNG gods hoping it doesn't spawn there especially in the later game. Perhaps there could be a better way to be able to push back the time that doesn't depend on this random spawning?
I do appreciate that there's some leeway in the edge of the red zone though.
