I'll have to disagree, people only ever raised concerns (and valid ones considering this will end up being a paid product one day) when the Devs started to delay updates and make basically no progress. Even now some people are trying to defend the Devs absence, which I'm very baffled by. Since all it would have taken to avoid this mess, is for them to log in, just say whether the project is discontinued or not and refund people if it is. There's no shame in discontinuing a game, but there is in not being responsible enough to let everyone know and return the money people have invested, in hopes of ever seeing the finished game.
Honestly, this is the first time I've seen such patience and kindness from fans in game development on something that is trying to basically sell itself for 4+ years and has kept making empty promises to its own customers. That's my own take, the very least.
