Slap Friends



A 2-player fighting game where players slap each other with cartoon characters. Players control the game by wearing physical costumes with accelerometers tracking movements, allowing actual slap fights with the costumes. I built the game in Unity, and used Arduino for controller software and hardware. Concept, art, and costume creation was by Terence Tolman.

Slap Friends was featured at Alt.Ctrl.GDC 2016, GDC Experimental Gameplay Workshop 2016, and Indiecade 2017

A Star Fox inspired space shooter where players are under attack from the opening title crawl of the story, and have to fight their way through a very meta experience. Currently in development as a solo endeavor

Platforming game about collecting words to decode a monster language and eventually communicating with the inhabitants to progress in the game. Made with Unity for Ludum Dare 33, with the theme "You are the monster." Conceptualized by me and co-programmed and co-designed with Omiya Games
