1. If any lousy streaming website can have some "please donate" box, where people can send money, why not just add one here?
2. Could also start a Kickstarter campaign to get enough funds.
3. For 2., be more transparent, lay out next developing steps, maybe even get someone to manage community forums. So players receive information and you can focus on developing.
4. Think about Sundays! I'm really new to this game, same for most guys in my league...and the #1 complaint is the 3 days between games from Saturday to Tuesday.
If you already lost players, 3. and 4. might be the reasons for it.
Awesome game, don't think there is something similar available right now. Please don't waste that!
