This trailer offers a one-level pitch video for Schein, a puzzle platformer developer Zeppelin Studio is looking to fund through Indiegogo and get approved by Steam Greenlight. In short: "In Schein light is the key to everything: Defeat deadly beasts, solve tricky puzzles and uncover hidden paths through the murky swamp." This page offers a "Dev-Demo," which is currently at version 0.3.3, but will apparently not be for long, as they explain: "This Dev-Demo is different from a regular demo, because it will be constantly updated in the course of our development. That way you can see how Schein evolves and improves."
