Every level is the first level (really easy):
96 09 00 08 21 07 ?? 00 00 00 08 03
96 09 00 08 21 07 01 00 00 00 08 03
This game keeps going (even past 3 levels), so when you reach your desired score, end game and send score.
The review score is 3500, but i wouldn't really submit a score over 3400 unless you really want a trophy.
