“it hit me with nostalgia in a way that a lot of these...'nostalgic' games just don't do for me”
"I was very torn between who was going to #2 or #3...the tiebreaker was going in and seeing all the changes that the developer made [post-release]"
Mark @ The Electric Underground

"I try to focus mainly on console games, but...I have made an exception in this case and now it's my most played game on Steam in the past several years."
Jason @ I Do Games

“everything is measured to the millimeter so that the experience is as satisfactory as possible....Iori Branford has graduated with a superb degree, unashamed, profound, intelligent, full of justice and feeling.”
Santiago @ Isla de Monos

"I have played 3GB indies that had less options.... In Demonizer the enemies...sneak back behind the trees and stuff... really a 16MB game! Who knew?"
Cole @ The SML Podcast

“very entertaining STG for new players to the genre...does a really good job accompanying with a simple tutorial, easy mechanics and makes it very quick to practice any level you want.”

Artistic statement

Demonizer is my most personally meaningful work. Bringing together all that I love and believe in - exhilarating gameplay, charming fantasy characters, the ideal of peace and justice for all - Demonizer indulges a fantasy of changing hateful hearts and minds, and presents an ode to the outcast and oppressed youth fighting the cruelty and injustice of the old world.

Various pieces of Amelia and friends commissioned during development, showing bits of the world she is fighting to protect or just letting her meet other original characters. I enjoy the diversity of styles and interpretations.
