In my opinion, the reasons for why some of your games went viral unexpectedly (like Bedrot, Dress Me Down and Mukbang Idol) are because of their simple premises and short playtime. As social medias and AI contents have continued to fry people's attention for the past 3 years, the mainstream audience in general would barely touch games with complex themes, slowburn horror or story rich games, combining with the fact that games are being produced in vast quantities and fast pace thanks to AI (again), competition is fiercer and there is not enough regulation to determine which game is worth being put out there, people also become more reliant on big well known content creators or internet trends to decide whether or not they should check something out, it's also a double edge sword cuz you know going viral (like in Mukbang Idol) can have dire consequences, or can be annoying as hell if one your games manages to spawn in a fanbase and everything only goes down hill from there...
This is not to say it's impossible to maintain a lowkey successful indie game dev status, there are indie devs on this platforms who made some really gut-wrenching games that were somehow able to reach their audience and get the support needed to continue their gamedev journey, yet their works rarely or literally can not be shared on other social platforms due to how graphic they are, meanwhile indie devs who try to cater to popular streamers and content creators by making the same types of popular games over and over again would usually profit in the beginning, but in the long term they can't exactly make a name for themselves and still struggle to maintain success, this is something people have to figure out by themselves until they can make the one game that change their gamedev career for good, which can take years to happen.
As a small content creator who also struggle to keep up with the algorithm and the viewerbase engaged, sometimes things just don't work out and lots of effort go into waste, but only from there could I learn something new, it's all part of the process so don't beat yourself up about not performing as good as you used to, and continue doing great things.
