PsiloSybil is a classic linear 3D platformer with a faithful mid-90s look and brutal difficulty. You must guide plucky mushroom Sybil across a colourful world of devilish traps and defeat the evil master of all hogs, Lord Nutmeg, to set free all of shroom-kind. In each of PsiloSybil's handcrafted levels, alternating different playstyles and aesthetics, you'll meet a unique mushroom character held captive by Nutmeg's boar minions. Freeing them is not going to be easy!

The game also provides time trial challenges, and an optional arcade mode which reintroduces lives and removes collectables. It is also perfectly deterministic and employs no RNG, which makes it perfect for speedrunning.

PsiloSybil strives to reconstruct the classic look of PS1 titles. Not only are the world, characters, and objects modeled and textured with the limitations and visual trends of the time in mind: a full suite of visual effects ranging from vertex snapping to an emulation of composite analog video enhances the experience. All of this is customisable and you have detailed control over each component.
