I love that you are so sure about this. Hopefully your conviction is true and Nyx will not abandon the project.
Why should she? Just because some players have no idea how much effort it takes to make a game and are mistaken in assuming that one person can deliver an update every quarter in their spare time? There are two options for devs: 1. small updates with little content and therefore short times between updates or 2. longer waiting times but a decent amount of content. Personally, I'd rather wait a few months and then have one, two or more hours of playtime instead of getting an update once a month, which I can finish in fifteen minutes.
It is incomprehensible to me why there is always such impatience. Nyx is transparent about the development process. She regularly gives information about what she is doing and what is still to come. She explains in detail when there were problems and even when she wasn't able to work much on the project. Unlike some other devs, she never lied. At least as far as we can tell. On the contrary, she has now delivered numerous updates. Sometimes the waiting time was longer, sometimes shorter. Apart from your own impatience, there is no reason to panic like this.
And quite apart from that: even if the development should be stopped at some point. 99% of the people who panic like this didn't pay a dime. So why do they care? There's one rule: only pay a dev as much as it is worth to you. If a game is abandoned, you haven't paid more than it's worth, so there's no reason to be angry or worried. But let's not kid ourselves. We're on a piracy board here. There is always a lot of talk, but there is mostly nothing behind it. We take the games for free, believing just because you play them that you have any rights to anything. Nyx owes us nothing, only her Patreons. Although, no, neither do they. Donations are donations. The principle behind a donation is that you shouldn't expect anything in return. It is different when buying. When you make a buy, you pay for something in return.
