You do realize this is a small, indie dev studio, right? We're three weeks into this and you are upset because we haven't seen major gameplay changes yet.... these people can only work so quickly. I'm sure they are listening to our feedback, but there isn't a magic switch they can flip to implement the changes we're asking for. It's also quite likely that the build we are playing isn't the only build floating around the developers office. No doubt they are working on experimental features or gameplay mechanics that are unfinished and not yet release worthy.
Be patient, dude. Just because our feedback hasn't been implemented yet doesn't mean it hasn't been heard. To the devs: I think i'm just going to start signing every post with this. This is why we need a roadmap. Unless you tell people what you're working on behind the scenes, your product is only going to be taken at face value.
