Control the amplitude and the frequency of the sinusoidal wave signal to guide the U.F.O. through a never-ending asteroid field, collecting upgrades in the meantime! These upgrades will help you further manipulate the waves.

Controls

• A/D or Left/Right arrow keys: Change Frequency (lower frequency/higher travel speed makes systems reboot quicker)
• W/S or Up/Down arrow keys: Change Amplitude (narrowing the signal will drain energy proportional to the amplitude difference)
• Shift: activate Phase Shift, an ability that allows you to dash
• Spacebar: activate Phase Inversion, an ability that flips the sine wave, and teleports you to the corresponding location (not available from the start, needs to be chosen as an upgrade)
• Esc/Tab: pause

Systems

Shield

Your most basic and easiest to use system. It’s passive, and prevents the U.F.O. from blowing up when hitting an asteroid. After blocking a hit, the shield will take a while to reboot. The slowest to reboot system on the U.F.O. You will know when it finishes rebooting.

Phase Shift

An active system that gives the U.F.O. a sudden speed boost, shifting the wave signal. This system is the fastest to reboot. When the system is available, the outer circle of the U.F.O.’s body is glowing blue.

Phase Inversion

Another active system, one that flips the wave signal upside-down, and has some interesting side effects too. The U.F.O. emits blue rings from the bottom to let you know when this system is online.

Upgrades

After every wave of asteroids, a choice of 3 upgrades is offered. These range from upgrades to energy capacity and system reboot durations, to some bigger upgrades, such as Phase Inversion destroying every asteroid on the screen, Phase Shift giving the U.F.O. brief immunity, and some more!

Technical limitations

While the game should be playable on all resolutions, the game works best on monitors with 16:9 aspect ratio or something close to it.

Patch notes:

Added a fix for the bug that caused the screen to break when opening Settings in the browser.

Fixed an issue where using Phase Inversion would break the music in the browser version.
