Crush stupid robots beneath your feet! Wield your extra-terrestrial powers in the defence of humanity, and send those alien invaders back from whence they came! This is Yoink. -.PP -You play the part of a flying alien heroine who must defend her home on Earth -from other airborne alien invaders.

Basic arguments include: .TP .B -h, --help Display basic usage information, and exit immediately. .TP .B -i, --info Display build and environment details, and exit immediately. -.br .SH TIPS -.PP To attack, you must dive on the enemy at high speed. If you're going too slowly, you'll just drift harmlessly by. Diving from above gives different -results from swooping in and hitting them from the side. If you're too close to -attack, try to build up speed by running away and bouncing off a nearby -building! -.PP -By charging your special alien powers, you can throw fireballs. The orange bar -at the top of the screen represents your power level--at maximum, you can -destroy almost anything. Aiming can be tricky, but with a little practice it's -quite easy to launch them in the right direction. Try doing a little swoop or -circle in the air to line yourself up before releasing your fireball. -.PP +results from swooping in and hitting them from the side.

Possible values are 1, 2, or 3 where 1 means the least -amount of detail and 3 means the most. This effects the number of objects drawn -to the screen. A high level of detail will draw everything but could cause poor -frame rates if the graphics driver can't keep up with the load. Lower levels -will omit certain details which aren't crucial for playing the game with the -possible benefit of higher frame rates. See the Notes for more ways to increase -the game's performance.

You can set this to a very high number to effectively render -as many frames as is possible, but the actual rate could be limited by vertical -display synchronization, depending on the X11 driver and settings used.
