Play Yoshi no Banyu Inryoku (J)(WRG) Online

Yoshi no Banyu Inryoku is a Japan-only Game Boy Advance release, developed by Nintendo. It came out during a time when the GBA was full of inventive platformers, and this one stands out for its unusual central mechanic. You don't see many games built entirely around manipulating gravity.

You control Yoshi, and your main goal is to navigate through a series of puzzle-platforming stages by tilting the entire environment. The core action involves rotating the screen to change the direction of gravity, sending Yoshi walking up walls and across ceilings. You'll need to collect a certain number of items in each stage to progress, often while avoiding enemies and navigating environmental hazards. The pacing is deliberate, focused on solving spatial puzzles rather than speed, and the difficulty comes from planning your rotations carefully. It feels surprisingly tactile and clever, like you're physically tipping a little diorama to help Yoshi find his way.
