@the dev, if you want me to shut up and delete my comments, i will
"development hell" is a term that is used when a project has been delayed indefinitely because of internal factors like a lack of competency, people not being paid, conflicting concepts that have not been resolved, high stress work environments, bad leadership/management, etc.
a single dev not updating their freeware on itch.io after a year or however long is not 'development hell.' it's just life.
speaking as a creative writer and a coder, there are few things more irritating than someone blowing up your account, DMs, inbox, comments, whatever repeatedly asking for updates when you don't owe them anything. of course it's lovely that you like a person's project, but projecting your disappointment at their speed in creating it is the worst, most entitled way you can express that. your sadness is irrelevant to my comment and from the way you've described it, asking for updates over and over, it sounds like you've been pestering this dev for a while.
as for behaving: i speak bluntly. you don't have to like that.
