Boy and His Blob, A - Trouble on Blobolonia
A Boy and His Blob is a puzzle-platformer developed by Imagineering and released on NES in 1990. Players control a boy and his shapeshifting blob companion through various levels filled with obstacles and puzzles. The core mechanic involves feeding magic jellybeans to the blob, which transform it into different forms—a trampoline for jumping, a bridge for crossing gaps, a bomb for destroying obstacles, and many other useful shapes. The game features six main worlds with multiple stages each. Controls are straightforward, with players moving left and right, jumping, and selecting jellybeans from an inventory menu. The levels emphasize creative problem-solving, requiring players to figure out which blob transformation is needed to progress. The game combines platforming action with puzzle elements, creating a unique experience that relies on resourcefulness and experimentation.
