Blue's Journey , released for the Neo Geo AES in 1970, is an action-packed adventure game that follows the story of Blue as he attempts to save the planet of Raguy from the Daruma Empire. The Daruma tribe has invaded the planet, spreading pollution and turning its inhabitants into slaves. With the help of some friendly characters and useful items, Blue must use his wits and cunning to defeat the enemy forces and restore peace to Raguy.
Gameplay in Blue's Journey is fast-paced and challenging, as players control Blue as he navigates through levels filled with enemies. The game's unique mechanics involve using a leaf as a weapon to whip enemies upside-down, and then hurling them at other foes. Players can also collect flowers to use at the shop, where they can purchase items such as stamina boosters, swim fins, and light safe to aid in their progress. Other characters may offer assistance or obstacles, depending on how truthfully players answer questions.
As players progress through the game, they will encounter bosses that must be defeated before a mysterious figure in a devil suit appears with a tempting offer. Players can choose to accept or refuse this offer, which affects their progression and rewards. Time limits apply, adding an extra layer of pressure as players navigate through increasingly challenging levels.
