Actually, it might be better to simply release the game once it’s content complete.
Personally, I’m also pretty bad at sorting through the WIPs on the forum and looking for some to comment on. If I see a WIP I don’t recognize with a substantial number of comments, I subconsciously assume it’s something which didn’t catch my interest sometime back and ignore it. That’s also why I tend to comment on new WIPs, even if most of these will never make it to the next chapter. Perhaps I need a way to fix this. 
But… if anyone wants feedback on a WIP, feel free to reach out. (But I reserve the right to decline if your project has plenty of attention already or if I’m busy.)
