Just started the early access and I've gotten in a few games. Considering your still in an early tech preview state, I'm checking on what kinds of feedback are actually useful to you right now.
Right example, I have a number of balance and numeric thoughts, but my guess is you don't care about any of that at the moment, its more fundamental systems and the like. Just give me a quick understanding of the areas you are looking for feedback, and I can provide some!
