Super-polished entry which gave me a lot of fun! I'm amazed by how you managed to have six different people working on this, and still the final product seems so coherent and well-directed! All the artistic aspects were spot-on: from visual effects to environment art, from music to voice acting, from character design to UI graphics, everything contributes to create a strong mood, which I totally loved. You did an amazing job as a team, congrats!
Speaking of mechanics, the simple idea of choosing which units to control, knowing that the others will become your enemies, is fantastic. I've never seen it implemented in a turn-based combat system, and it has so much potential that I'm kinda sad you only had nine days to explore it :P
I'm looking forward to your next release ^^
