1. Undertale Yellow - So it seems a lot of people mistook this for a sort of "Underswap Yellow" in the beginning, so changing our name would eliminate that problem

2. Way to specific - with a name like JusticeSwap, you'd expect Justice to be present everywhere you see. Well Determination in Undertale wasn't named DTtale, so it seems a bit odd in hindsight

3. Confusion - I feel like JusticeSwap doesn't really convey the exact message i envisioned when at a conceptual level

4. more openness - Similar to #2, but more so in the sense we don't have to worry about catering to making "Justice" always prominent

Closing Notes:

Don't worry however, as Atlas is still the protag of the game, and they still have their soul of justice. Nothing content-wise is affected by these changes, only minor changes to the image of the game are accomplished.
