Released back in 2018, Crashphalt is a free and eccentric multiplayer game in which players do ground-pounds to send out seismic ripples, striving to punt each other off-screen. It's got an "overwhelmingly positive" Steam user review reception, as of writing, but that's not entirely a judgement on its quality. You see, Crashphalt is a hit today partly because you need it to run an online multiplayer mod for Toby Fox's wonderful RPG Undertale.

Of Crashphalt's 555 currently existing user reviews, the vast majority were written over five years after release, and either totally disregard or cruelly dunk on Crashphalt. An example: "10/10 Funny Undertale game, will never play this."
