Not sure if this counts "yet", but just beat Downwell, which is getting a physical release on Special Reserve Games in the near future.
Special bonus super #humblebrag, but after about a zillion attempts I beat the game start to finish in one continuous combo, without ever landing once until the very end, with 100% health intact. The developer Tweeted me a congrats and everything, it was a true proud nerd moment. Can't take a screen shot any further than this without spoiling the simple (literally one screen) yet somehow super effective ending of the game.
