"I dunno why they chose Crashphalt": forgotten Steam game suddenly becomes a hit after players start using it for Undertale online multiplayer

The free-to-play multiplayer game Crashphalt, released in 2018, has seen a surge in popularity due to its use in an unofficial Undertale online multiplayer mod. Players are downloading Crashphalt's files to enable co-op play for Undertale, leading to a flood of reviews for Crashphalt that reference Undertale. Developer RetroSpecter is philosophical about this, noting Undertale's inspiration on their game development journey and even playfully suggesting a collaboration with Toby Fox.
