Thats exactly how roadmap works! You make one and then execute it over time. So far Tvale is ading everything whats written on it to the game. Missing only few things like "actual animations" and "store". When he will finish this roadmap i believe he will make new one! Also check other channels on Discord like Development and shit, FAQ - SMA, General where he makes everything clear. For example he wont answer on things like
"I shat in my pants yet i do not notice"
That should be your quote.
Patreon works like an investment, and worst thing for any investment is uncertainty. If you can shove your ego to somewhere sun does not shine, and stop trying to be snarky for a moment you may actually realise it's s problem that can and will hurt the game in the long run.
In a game developement a thing you had 2 yeas ago is a thought, not an actual roadmap. Dev is so silent that people are asking if it is abandoned. I know it's not abandoned, you know it's not abandoned, but it's not how others will percieve it. If dev is so forthcoming and answers to patreons where do they invest their money at, do tell, what's planned for the next update?
And no, that's not how roadmaps works.
