If you send “feedback wanted” mails in our in-game messages, it would be nice also to provide a link to a thread on this forum rather than just Facebook-only link. As you know, many of your players do not use Facebook. This of course is much less important for “competitions” like ‘which magical beast is this’ but very important if you actually are asking for player feedback.
The previous “competition” for Alchemy’s secret bonuses was also posted into this forum, so I think this could happen.
Important note: I am extremely grateful to Pixel for providing this forum so that non-Facebook players have a way to communicate both with the Diggy team (indirectly) and other players (directly). This post is not meant as a criticism in any way.
