Before the duo can sneak again, they must walk some distance away. This can be hard to come by once more obstacles come their way. The game ends when Jerry and Nibbles cause enough noise to wake up Tom. You must also avoid firecrackers. Tap on the firecracker to prevent Nibbles from lighting it. Leaving it alone will surely wake up Tom. Moreover, the noise meter doesn’t reset, no matter how far you go. Even if you’ve managed to avoid hitting anything, you might still wake up Tom if the meter is high enough.

This is a simple game that demands quick reaction times and careful timing. You don’t want to sneak too early because it’ll use up too much of your meter. Likewise, you shouldn’t release too soon since you’ll cause noise anyway.
