PsiloSybil

PsiloSybil is a linear 3D platformer with a mid-90s look and challenging gameplay. You guide Sybil, a plucky mushroom, through a colourful world of traps and defeat Lord Nutmeg, the evil master of all hogs, to free shroom-kind. Across 25 handcrafted levels, each with its own playstyle and aesthetic, you encounter a unique mushroom character held captive by Nutmeg’s boar minions.

Levels and challenges

The game includes time trial challenges and an optional arcade mode. Arcade mode brings back limited lives and removes collectables. PsiloSybil is deterministic and uses no random number generation, making its challenges consistent for speedrunning.

Visual style

The world, characters and objects recreate the look of mid-90s PS1 titles, using low-poly models and period-inspired textures. Visual effects include vertex snapping and an emulation of composite analog video, and each effect can be customized with detailed controls.

Characters and secrets

The game features a large cast of fully animated low-poly characters, along with hidden and additional content for players who like to collect. Its old-school gameplay is fast-paced, with responsive controls that are easy to learn and challenging to master.
