You keep linking to that archived topic in response to these requests and this continues to be a completely inadequate response. An obscure URL text command that cannot be combined with other filters is NOT a reasonable solution to this problem.
People "ask all the time" because you haven't solved the problem.
Itchio needs actual robust filtering options in its interface as has been described in detail on this forum many times now. This should be a much higher priority for the site as it significantly affects its usability making it very difficult to find games, which makes people not want to use the site to look for new games, which is bad.
