We've received several reports of popular games such as Amorphous+ going missing, which I'm sure must have been most distressing for many of you!
Fear not, I think we've figured out why this has been happening. As you know, more developers have recently been working on optimising the site so that it doesn't 'lag so much' and 'break' (both common and valid complaints we hear about), after which the administration will be able to implement changes to the site much more easily.
A side-effect of this is that certain game files might go missing. As far as I know, they were not intentionally deleted, nor is it a permanent loss, as we should be able to recover them as soon as we figure out precisely what's going on.
In short: your favorite game missing? It's not gone forever: We'll get it back soon!
... If you click on the shooting category link, the sorting method "dates" says "no games were found". I went to plays and it seems like all were there, but this should be looked into.
