I've seen the face swap mechanic a few times, but so far this game does it best.
A nuclear throne style top down shooter. I've seen some games that reroll the dice when you dodge/roll so you could possibly implement that as well.
Not much to say that hasn't already been said. This game is a handful of QoL tweaks from being a full commercial title. Gameplay is juicy, sounds are great, and mechanics work well without needing a bunch of explanation.
Pick up and play. Only downside is this isn't playable in browser.
