And here is current WR route (to not watch whole 50 min video again):

I would recommend to pick up these items for safety (not mentioned at the map): Area 3 (before corridor fight): Shield and Red Lander Area 5 (before corridor fight): Blue Lander Area 6 (before corridor fight): Shield and Fireball Area 7 (after corridor fight): don't die after corridor, kill red crab at Area 6 to get Red Lander and buy another one for 600 chips higher Area 10: buy Fireball if you got 2000 chips

There are also some EE at the map if you lack them/learning the game.
