Nobody is good at everything, so if a developer creates a game without considering others' opinions, the project usually won't succeed. In this game, I see this issue. The developer didn't listen to feedback and criticism from other users; instead, they continued doing things their own way. I notice that their Patreon support has dwindled, so I assume the project has naturally come to an end.
Sadly, I have to agree. It was the lack of updates that really killed this game before it even got started. I did try to warn the dev about slow updates and offered my support, but it cannot be helped if there is no effort from the dev's side.
It was probably just a hobby for him, something to do on the side, because the Patreon support didn't really grow enough to justify working on this full time... but the lack of communication, no roadmap, rarely any updates or posts about the progress... It all piles up and makes it hard to support.
I'll hold out for a few months before assuming this is dead and abandoned, but the Patreon support has dropped drastically so it might truly be the end unfortunately. I'm still surprised there are a few paying customers, but it's hardly $16 and not enough motivation to continue.
