added credits screen
simplified level name
eye can unlock laser
ok to put tree if non-empty -- less error-prone
moved eye definition out of level code

moved generateDesert outside of main body
instead of unlocking laser, treat as trap, more natural and fixes a bug
kill player if gets too far from eye
added "to be continued level"
cut out the sound, I hope...
