with kongregate having very few new games most of which being idles of questionable quality i am looking for other platforms that offer more and better quality games. Aside from steam do you know if there are other platforms/sites where games can be found? I am aware of itch.io but it has too many games and finding actual games instead of prototypes seems like too much effort. All suggestions are welcome

As burrubu said, Armor and Newgrounds may be the way to go. Are you deliberately after browser games or are you willing to download etc.

As you mentioned steam, I assume you have looked at things like Epic (I know this is contreversial, but they do offer free games fairly regularly).
