PSPMarble is a homebrew game that adopted the style of the “Marble” game (remember that old retro game?), but also extended the gameplay to 3D, with physics and some new gameplay ideas.

Changes:

COMPLETED REQUEST regarding the camera system (wrapping is allowed now). Requested by “the underminer”.
UPDATED physics module, now marble goes a bit faster, but the controls remain accurate, and they won’t make your life harder with “puzzles”.
UPDATED stacked particle system for smoother animation.
UPDATED session cache manager, and now the load times while you switch menu-related session are improved.
UPDATED an input event in the tutorial mode.
Plus more not-so-worth to mention.
