I have played both the closed alpha and the demo and I'm uncertain about one thing. In the demo after you die you awake in your hub or lobby and in that lobby you can use your soul crystals to buy permanent upgrades for the next time you enter the labyrinth. However from what I have seen of the closed alpha it looks like this feature is not present. Is the lobby not implemented yet or have I not gotten to a point in the game where I have seen it, or was the idea completely removed?
