LoK, here are some of of the best flash games I've ever played.
If you haven't tried them, you will want to, after you play them for a few minutes.

CrossCode (Currently a demo, steam early access exists. But it's a pretty good demo, it feels like a full game.)

Ge.ne.sis (This one is just phenomenal)

By far, I honestly think ge.ne.sis is the best flash game I have ever played in my life. It's just stunning overall. These three aren't necessarily the 1,2,3 of the best flash games I've ever played, but they're ones I would reccomend to LoK.
If you haven't played any of these and you have about ten minutes spare time, these are three games that you should play.
