No need to be sorry! I'm happy you're interested in the storyline! :D I'll try to answer all your questions here:
- As long as you credit me and link back to this game, then you can use the storyline for your AU.
- Also, no. Sans does not know that the player changed their name. Only Flowey knows and will mention it.
- There is not a SOUL-less option. Only the six traits are the possible options.
- You don't need to buy WinZip to unzip the game. Normally on Windows, you're able to unzip it by right-clicking on the zipped folder and selecting "Extract All..."
Make sure "Show extracted files when complete" is checked, then click "Extract."
