Comets are flying at your space station! Type the word on each comet to zap it. Start with two keys and learn the whole keyboard. With 3D glasses the comets fly right out of the screen!

Do you have 3D glasses? Red-green, red-blue and red-cyan glasses all work.

How deep?
Less depth is easier on the eyes. More depth pops out more.
1. Hide the green bar
Put the glasses on and cover the eye behind the green lens, so you look only through the red lens. Slide left until the green bar disappears.
2. Hide the red bar
Now cover the eye behind the red lens, so you look only through the green lens. Slide left until the red bar disappears.
3D mode is just a fun way to play. If your eyes feel tired, take a break or play without glasses.
HOW TO PLAY
Each comet has a word. Type the first letter and your laser locks onto that comet; type the rest of the word to zap it.
Use the keys on the screen, or a real keyboard. The keys for this lesson are white; the others are grey.
Home row: rest your left fingers on A S D F and your right fingers on J K L. F and J have a little bump on a real keyboard (yellow here) so you can find them without looking!
If a comet reaches your station you lose a ❤️. Zap every comet with no misses for ⭐⭐⭐.
Each lesson adds new keys, until you can type every letter. Coins buy extra shields, slow-motion and laser colours.
HOW 3D WORKS
Try this: look at your finger with one eye, then the other. It jumps! Your brain uses the jump between your two eyes to see depth: stereo vision.
The game draws space twice, from two eyes a little apart, in red and in green (or blue). The glasses give each eye its own picture, so far comets are deep inside the screen and close ones fly out at you.
Why the funny key order? The QWERTY keyboard was designed for typewriters in the 1870s. Letters often typed together were spread apart so the metal arms would not jam. We still use the same layout today!
