and
Rouge One - https://itch.io/jam/gmtk-2019/rate/461305
instantly recalled both when I saw this topic, generally for the same reason. Heaps of polish, fun twist on the theme. Platfaller's use of shooting to change platforms makes for some really high skill stuff and rouge one is a ton of fun in trying to balance good and bad stats with one number. :)
