Even though it's not entirely in the spirit of the site, a textual filter or search would be nice.
Feel free to add these games:
(Pandora exclusive, will also get a huge update soon-ish. Even though the category on the repo says "ArcadeGame" it's more of a Logic or Puzzle game. It's open-source, too.)
(Port, would put it in the adventure or puzzle category, it's very hard to pin down though. Game is FOSS - public domain, even)
In general though, I would like to see this sort of functionality integrated into the repo (so we don't have two websites with the same purpose).
Even though the intent is different to the repo's right now (showcase of good products vs. database for everything), I think these can be combined.
Taking the Steam store as an example, you will never see a games like this
on the frontpage because of content management. If you provided the repo with a list of "certified good" games or reviewed games (something you are creating right now), you could have the same thing, automated even.
Just the presentation of the repo's frontpage need to be adjusted (along with features like videos, icons for c4a functionality, etc.), but I guess you could combine efforts here (instead of working on separate projects).
This is why I would like to see the repo going open source (something on which @milkshake
sadly hasn't commented yet).
For now, though, keep up the good work.
