Afk Heroes doesn't save progress. Yes, I am logged into my Armor Games account. Is anyone else having this issue? Is there a solution or is this yet another game that the devs have abandoned like so many others?
I think the issue is on your end. AFK Heroes saves just fine for me. Make sure that you have cookies enabled and assign your browser enough memory to properly store local save files, as well as not regularly clearing out your browser cache or temp internet files... which can lead to local save files being deleted.
Also, AFK Heroes is a standalone, single player idle game. It's not an actively developed game, so attacking it for being "abandoned" is inappropriate.
