Feverwave: One Button Wave

Feverwave is a one button arcade game where getting close to death is how you score.

Hold to rise, release to dive, and steer a neon arrow through a twisting corridor. The closer you fly to the wall, the faster the Fever bar fills. Fill it and FEVER hits: three seconds of invincibility and 5x score while the whole corridor lights up. Play it safe and you will survive, but you will never see Fever.

GRAZE OR PLAY SAFE
Every wall is a risk and a reward at the same time. Graze charges Fever quadratically, so a hair's width beats a comfortable gap by a lot. Coins sit right on the graze line, where taking them means flying where you should not.

30 HANDCRAFTED LEVELS
The curve is built, not generated. Level 1 is a gentle first flight. Then speed, narrow gates, fixed obstacles, moving blocks and gravity flips arrive one screw at a time. Every level has three stars: finish it, see Fever, and collect 75 percent of the coins.

ENDLESS, DAILY AND GHOST RACES
Chase your own best in Endless mode. Take the Daily run: one seed for everyone, one attempt worth bragging about, and a share card at the end. Or send a Ghost Race link to a friend and watch their run fly beside yours.

PRACTICE WHEN YOU ARE STUCK
Stuck on a level? Practice mode drops checkpoints every 15 percent so you can drill the part that keeps killing you. Practice runs never touch your records.

TINY, OFFLINE, NO PERMISSIONS
No ads. No in app purchases. No account. No tracking. Feverwave does not even ask for the internet permission, so it cannot send anything anywhere. The download is about 3 MB and it opens in around a second. It works on old phones and in airplane mode.

16 COSMETICS, EARNED BY PLAYING
Trails, arrow skins and corridor palettes, bought with the coins you collect. None of them change the game. Skill is the only thing that moves you forward.

CONTROLS
Hold anywhere on the screen to rise, release to dive. That is the entire control scheme. Landscape only, because seeing far ahead is the game.

Feverwave is built for short sessions, instant restarts, and that one run where the bar fills at exactly the right moment.
