what law? i didn't hear about the fangame act of 2024
In what way? Kamala-Tale uses Undertale's themes and gameplay as a means to give commentary on not just American politics, but even Undertale itself (Ben Franklin saying the Genocide route sucks), which puts the game squarely in the realm of fair use. While its art, music, and other aspects are SIMILAR to Undertale, the important distinction is that it ISN'T Undertale, and the only shared aspects come from the nature of it being a parody (i.e. the track "White House" resembles "Ruins", but that's part of the joke. If it didn't resemble the original work in some way, then it wouldn't be a parody.)
