How did you four manage to develop this game in a week lol. It's very polished! The gameplay is unique and enjoyable though a bit punishing at times (I died to the last boss after three tries) and the art style and soundtrack are very fitting. This feels like a demo for a full game and you can definitely turn it into one and put it on Steam.
I'd really love to see a way to revive party members! I lost the guy that gives you mana pretty early on and felt like I missed quite a big part of the mechanics.
