Please let us know when you completed a quest or investigated new content with success (or, just no problems). It is not just negative, "I think I found a bug" feedback that is useful, although obviously if you find a problem you should report it. That includes even very minor things, such as typos or bad grammar. Positive feedback is also very useful. We are not looking for praise, but knowing that several testers made it through quest "XYZ" and didn't find any problems is valuable, because it means we know that quest was independently tested.
Thanks in advance to all that are willing to put the beta version through it's paces. We know it takes quite a lot of time to do this (because we have done it, more than once ), and when the release version is posted to Google Play you will have to do it again. The support of the AT community is what keeps us going though, and makes AT possible.
