My game: https://nitai99.itch.io/twisty-chess
Twisty Chess is like chess except every couple of turns you can choose one piece of yours and change it's type. There's a little bit more balancing I did though, of course.
Another amazing game: Clumsy Clones
A platforms where you can't jump but you can live behind clones that make you jump when you hit them while in mid air, and then redo the level. It's really good. Believe me.
