Definitely one of my old time favorites
Play as Banjo as you can explore nine worlds and a hub world which is Gruntilda's Lair. Collect the Notes and Jiggies as you unlock the worlds before facing off with the last boss which is Grunty.
When you're first in Spiral Mountain, you meet Bottles as he forces you to train your moves. When you finally arrive in Gruntilda's Lair after training, you get the first Jiggy and unlock Mumbo's Mountain.
Mumbo's Mountain is the first world to explore. You can easily collect 10 Jiggies in this world and unlock the next world which is Treasure Trove Cove.
Treasure Trove Cove is where you first empty the water from the sandcastle before entering it. But you will need to solve the puzzles before earning a Jiggy to earn entering cheat codes and other codes.
Click Clock Wood is last and the hardest world, and it's definitely my favorite world. You will need to survive Click Clock Wood and collect the Notes and the harder Jiggies in order to defeat Grunty at the end.
The final battle with Gruntilda is much more brutal than any challenge of the game. You will need to try harder and defeat Grunty in order to complete the game.
The Stop N Swap is a secret. You can also collect the Stop N Swap eggs and the Ice Key by entering the secret codes. But, if you use two or more codes that aren't related to eggs or keys, then your data will be erased by Grunty.
Banjo-Kazooie is definitely a must-play for kids and adults alike. It is one of the best games I ever played as a child. I'll give this game a nine out of ten.
