Submission #2578: maTO's Genesis Wonder Boy III: Monster Lair in 18:43.07

Wonder Boy III: Monster Lair is a hybrid side-scrolling shooter and platformer design, spun off from the greater Wonder Boy series.

Movie features:

You lose 2 frames when you jump, so it's only done when necessary and when you don't want to kill enemies when it would add lag frames.

At the end of stage, if you have 9 or more health left, the wait time increases for 17 frames per health bar.

WEAPONS
There are 6 different weapons and they spawn in random order. Only way to manipulate the order is to "reveal" different number of them in the first part of the stages. Flame wheel is the only rare weapon, later every 20-35 weapon drop is Flame wheel.
-Flame wheel is the best weapon in the game against bosses. It's the only weapon that does 2 damage per hit and lasts for about one second before disappearing.
-Rocket's explosion can take lots of enemies with one shot and is really needed in Jungle to kill giant snakes. In walking parts you have to be careful not to create lag with explosions.
-Shuriken are excellent protection against enemies that are closing you from behind, up or down.

MEMORY ADDRESSES:
00FFDD41
00FFDD43 - two counters for boss hp.

1: BEACH (1 lag frame)
BIG FISH (96 hp - 8 frames)

2: JUNGLE (0)
SNAKE (?)
As you can see snake is different from other bosses. Can I say here we must color the snake?

3: CAVE (29)
BAT (72 hp - 8 frames)

4: COUNTRYSIDE (31)
NEST (96 hp - 12 frames)

BEE QUEEN (96 - 12 frames)
-Normally queen would move towards you every 63 frames, but I found out she could be locked in lower part of screen if you're on bottom two rows in front of her when she's about to move. So, I don't have lure the queen to go right. This makes the fight less entertaining, but it's probably the only way to win the fight without losing any frames.

5: ICELAND (0)
ICE MAN (96 hp - 8 frames)
At 10:10 he creates an iceblock which protects his hitbox. This prolonged his death for 2 frames.

6: DESERT (5)
CACTUS (96 hp - 7 frames)

7: VILLAGE (1)
MUSHROOM (176 hp - 2 frames)
Sometimes you can damage the heart in every frame.
Rolls are not manipulatable. Or at least I didn't find a way to manipulate them.

8: BEACH 2 (14)
25 sets of difficult crabs before boss.
GIANT ENEMY CRAB (96 hp - 8 frames)

9: SPACE STATION (5)
DRAGON RIDER (96 hp - 12 frames)

GHOST (144 hp - 11 frames)

I found improvement in Cactus boss, thus cancelling this submission.
