Toree 3D is a video game developed by Siactro, the professional name of independent developer Marcus Horn. Described as a "bite-sized 3D Platformer with a few weird elements", Toree 3D is a platform game inspired by the visual design and presentation of games from early 3D platformers. The game was originally developed for the Haunted PS1 Demo Disc horror game compilation in March 2021, and was later published independently and as part as compilations for the Nintendo Switch and Xbox. The game received a lukewarm reception, with praise directed to its visual presentation and sound design, with mixed reception of its controls and length. In September 2021, a sequel, Toree 2, was released by Siactro.
