I do NOT have a voice as I am not a supporter and nobody should take this as a biased opinion, but I do not understand. The Dev replied comments (as of October 25th) about this VN that its bigger than Chapter 4, but there's no news regarding teasers to keep up a hype.
Many VN creators tease their supporters for upcoming updates and news. You'll get more supporters if you have consistency on interactions means your goal will be reached. Listen, I always think the development of this VN is dead because it's been so long since the last update, but I want to be proven wrong.
Polarity was on my top 5 favorite VN when I saw a bit consistency around Chapter 2, but then dropped heavily over a year ago. Just because you do not have a schedule for the game at all, doesn't mean you shouldn't throw some teasers a bit and let your supporters know when you'll be finishing Chapter 5 after your few teasers.
Do keep in mind you still have actual supporters waiting for any update or news on your Paetron page.
By the way, if this project of yours is really dead like what the comments are saying (I REALLY HOPE NOT) and you're still receiving income from your supporters, you should be held responsible and refund your supporters after your last update information of 05/27/2021.
Do not take this as an accusation of any sort. This is more of a criticism and if its valid or not, I am fine with it. Thank you for taking your time reading this and have an awesome week.
