Belgian indie game studio Badass Mongoose has launched the demofor their atmospheric puzzle-adventure Helix: Descent N Ascent. It will participate in the February edition of Steam Next Fest, from 23 February to 2 March.

The demo offers a first hands-on with the black & white puzzle adventure, with about 30 minutes of gameplay and three abilities for players to apply in brain-teasing exploration and puzzle-solving, while your dark counterpart seems to sabotage your every move. ​

Helix: Descent N Ascent has a monochrome artstyle that draws inspiration from 1980s black-and-white indie comics, 1990s manga, and 1970s Franco-Belgian comics. With atmospheric music by Jim Guthrie (Sword and Sorcery, Nobody Saves The World and Below) added into the mix, it makes for an artistic journey to remember!
