I want to start by saying I understand your frustration when a newly released game does not reach your expectations, and nothing I say next is a try to undermine it.
Going in expecting every game you make to be a big success in numbers will only set you up for disappointment, I think the amount of devs that can truly expect to have success every time are very few and even the biggest of them have no 100 success rate.
Having a bad release does not mean the game will never get attention, I've seen it happen multiple times that an old game suddenly get a surge of interest and suddenly is everywhere, I've even seen with my own games how some only get attention during specific months and others I have no idea what happened before going down again. Some games become hits 5 years later, others only find very small audiences, we are too used to hearing the stories of small devs that become big overnight but those are the exceptions and for each of them there are thousands just as good (or even better) that haven't been found yet.
My advice beign something that has helped me, since I struggle a LOT self comparing my work with others, is as hard as it is, try not to focus on the goals you haven't reach yet and instead look how far you have come. You have 2,000+ people that are folllowing because they like what you do and that is an impressive number a lot of devs (myself included) dream of reaching one day.
You have more than one game that has gone viral which is huge deal, and you should be proud of that even if the next games didn't get the same reception. Think of how far you have come, even if there is still lots to do an improve, there is always something that could be better, but if you focus on that then you'll miss on all the great things you've done so far.
We also live very hard times as both creative creators and just in general, the world is suffering from en economic disaster, plus a never before seen amount of AI slop going around. Things are rougher today than they were 5 years ago, but such is life, it goes up and down and all you can do is keep moving forward and try again.
And risking to sound like an old granny, you are young, you have lots time to keep making games and keep growing as a dev and find that audience that loves what you do and waits eagerly for each new release. But sometimes that takes time, and is frustraiting and discouraging, but a lot of times all you can do is keep trying.
I hope you feel better soon and can't wait to see what happens with chapter two :)
