What genre is Towerfall Ascension, and do you have any favorite examples?

I'm specifically asking about the PvP part of the game.

This kind of game is my kid's favorite; we frequently play Towerfall, Duck Game, Rounds, and Hyper Contender (from UFO50).

It's so hard to find other games in this genre, because I don't know the standardized name, if it even has one, so I figured I'd ask here. What do you call low TTK platformer PvP shooting games? Do you have a favorite?
