Deliver letters... IN SPACE

You've taken a job as a delivery person in space, transporting letters to floating mailboxes. However, you soon find out that by 'letters' they mean letters of the English alphabet, not writings.

Send letters to the floating mailboxes with the left mouse button. The mailboxes themselves also have letters on them. If the letters on the mailboxes form a word, they will disappear and you'll earn points. You may also destroy an entire row of mailboxes with the right mouse button if they contain unfavorable letters (don't worry, the insurance company will cover for it). After destroying a row, your spaceship blaster needs to recharge, so only use it if it's really needed.

Also, the mailboxes will slowly move towards you due to gravitational influence. If they draw too close to your spaceship, it's game over, so try to be quick. The best five scoring players will show up on the leaderboard.

Note: this game may not work properly on Safari browsers or when using a keyboard other than QWERTY!

Lastly, some gameplay tips:

• Initialisms and most abbreviations do not count, as are words that are made up entirely of consonants.
• When a '?' appear you may decide for yourself what letter you will send. This can be any letter on your keyboard.
