Ethan sez,
Me and my colleague, Alexandra Keller, gave up our day jobs as web geeks to write this game, and almost two years later we finally have it:
Sky Alchemist – a puzzle game about transforming impure matter into pure forms, using heaters, coolers, and breakers, phase-specific collectors, and a centrifuge. We tried to be as scientifically accurate as possible – the heat capacities, hardnesses, and so on are taken from real data wherever we could find it.
It’s set in a rich world – a human society that has achieved “Victorian-level” technology, but with a twist – women are the dominant gender. We hope to expand more on this in future releases of the game.
He also notes that it’s DRM-free.
