Hi, when I say "closing down" I mean that sooner or later (could be a couple of months, could be more), I will disable new purchases here and hide the games for new customers. All games will stay visible (downloads available) for those like you who have purchased them before.
If at some point I decide to delete my account here, I will use the itch.io system that allows developers to send emails to customers so I can send everyone download links (you will be able to access the games for as long as you keep the links).
