I came across Iridescent, a difficult side scroller action adventure where you play as a plague doctor. If that sounds like something you'd like to play, check out the demo (full version is still in development). I'll add that when I say this game is hard I mean it. Seriously, it's harder then a lot of games people consider hard such as Hollow Knight.
