Indie Dev Surprised to Find People Are Using His Old Game to Play Undertale Online

Crashphalt, a little-known free-to-play Steam game, unexpectedly surged in positive reviews after players used it as a workaround to play Undertale online.

The Undertale Together mod and Steam Remote Play turned Crashphalt into a bridge for online co-op, even though the game itself was not the main attraction.

The story highlights how modding communities can repurpose an obscure indie game into useful infrastructure for another title.

It also shows how a small game can gain renewed visibility years after launch through player-driven experimentation and word of mouth.
