- Move with ← → or A / D
On a phone, drag anywhere in the sky to steer, or hold the large left and right buttons. Keep your finger down to move. Most obstacles approach from below. Sakura, phone airplanes, and late-game meteors dive from above after a warning.
- Two states. One second chance.
You start wrapped in a towel. A hit removes it, revealing her swimsuit. A second hit without a towel ends the run. After a hit, you get 2.2 seconds of protection.
- Catch a fresh towel
Collecting a towel restores protection and gives +100 points. Towels don't stack.
- Every second counts
Earn 10 points per second and 25 per dodged obstacle. Levels rise every 15 seconds with no final level. Desktop level 10 brings three-enemy formations, and speed keeps climbing with your score. Higher levels add more pressure. On phones, early levels have fewer enemies and more space between waves. Paired formations begin at level 6 on phones; the extra spacing gradually tapers off through level 9. Later waves bring tighter gaps. New enemy types unlock only as you reach their level.
- Read the new threats
On phones, airplanes dive straight down the amber lane after a 1.65-second warning. The lane locks at the start, and fresh waves wait for the plane to pass. Desktop airplanes cross a marked diagonal path. Sakura dives down the pink lane after a 1.25-second warning. Both lock their path when the warning starts. Balloons drift slowly and block more space. Drones track your position briefly, then commit to their target.
- Fall through four skies
Start in moonlit clouds. Level 4 brings a copper sunset, level 7 enters a storm front, and level 10 opens the aurora rift. Each scene keeps scrolling upward as it blends into the next.
Level 5: eagles dart sideways. Level 7: bats weave rapidly. Level 9: UFOs strafe across the sky. Level 11: meteors dive along an orange lane after a 1.4-second warning. Their path locks before they fall. All four can be cleared with the Nightmare Blaster.
- Catch the Nightmare Blaster
The glowing blue lightning pickup gives 8 seconds of automatic shots above and below Sarah. No extra button needed. Each blasted obstacle gives +50 points and disappears in a burst of sparks. The timer pauses with the game. Another pickup refreshes the duration; it does not make Sarah invulnerable.
- Choose your soundtrack
Both songs play in rotation and alternate between runs. Tap the music note to choose a track or adjust music volume. The speaker button mutes music and effects. Music starts after you press play and pauses when the game does.
- Collect the nightmare scenes
Reach levels 3, 6, 9, and 12 to permanently unlock one ENF ending at each milestone. Score 12,000 and 16,000 points to earn two more. Game over picks randomly from your earned scenes, showing unseen ones first and avoiding immediate repeats when possible. Before level 3, no ending image is available. Achievements stay on this browser, even if a later run ends early.
- Pause any time
Press P or Escape, or tap pause. Leaving the tab pauses the game automatically.
