yesss! Beat the game! This was pretty good! If no one minds, Imma post a walkthrough here for anyone stuck.
WALKTHROUGH:
ENTER YOUR HOUSE, DIVORCE WIFE AND LEAVE
GO AROUND THE PATH TO PROF OAK'S BUT AVOID THE 4TH TREE
GET POKEMON AND GO TO LAQUASH'S HOUSE, TALK TO HER.
NOW YOU CAN LEAVE. HEAD INTO TOWN, DO NOT ENTER ANY OF THE HOUSES. AVOID THE DRIVE BY SHOOTERS AS BEST YOU CAN, I FIND THE BEST WAY IS TO HUG THE HOUSES AT THE TOP AND WAIT FOR THE CAR TO GO BUY BEFORE MAKING A MAD DASH TO THE POKEMON CENTER AND POKE SHOP. HEAL YOUR POKEMON AND GO TO THE SHOP AND BUY THE COUGH SYRUP IN ANY ORDER. LEAVE.
THE LEAF IS NOW MOVED. HEAD UP TO THE NEXT SCREEN AND TALK OR PUNCH PROF OAK. PUNCH ALL THE OTHER TRAINERS IN YOUR WAY, WHEN YOU GET TO THE DUCK HOUSE, HUG THE WALL AND MAKE YOUR WAY TO THE DOOR. IT'LL SAY IT'S LOCKED. HUG THE WALLS BACK TO THE SPOT WHERE U WERE AND HEAD BACK TO BY PROFESSOR OAK. A KEY HAS APPEARED THERE. TAKE IT.
HEAD BACK TO THE DUCK HOUSE. THIS TIME, GO STRAIGHT AHEAD TO THE DOOR DO NOT HUG THE WALLS AGAIN.
TALK TO LAQUASHA ONE MORE TIME, YOU'LL BE ABLE TO PASS BECAUSE YOU WILL HAVE THE COUGH SYRUP. IF YOU BOUGHT SOMETHING ELSE SHE WILL JUST ASK WHERE HER PURPLE DRINK IS AND YOU WILL BE TRAPPED IN THE ROOM AND FORCED TO RESTART THE GAME.
IF YOU FOLLOWED MY EARLIER INSTRUCTIONS OR MADE A LUCKY GUESS AND PICKED THE COUGH SYRUP, THEN HEAD UP INTO THE ROOM ABOVE TO MEET A RUBBER DUCKY. CONGRATULATIONS. YOU'VE WON.
