There are patterns for the NES Pac-man, but the early levels
are fairly easy to get through without them.
Level 13 takes you up to the first key.
Unlike the arcade version, the ghosts NEVER stop blinking,
but the blink time gets very short.
Use savestates and rewinds if you get trapped.
Once you get to the upper levels, the 9th key is the last regular level.
From the 10th key on, there is one pattern. There is no killscreen,
scores go up to 9,999,990, but I usually quit at a million.
Here's my 10th key pattern, and score up to 310k.
