The art style changed because the sprites I used in the old demo were stock sprites. Stock sprites are sprites that can be used by anyone who buys them from the artist who created them. These sprites also have a limited number of expressions and, usually, only one outfit; so, if I happened to need something very specific for the story, it would have been difficult to add.

The other reason is that, by using stock sprites, I felt like the characters wouldn't have been 100% my own. Sure, I still gave them their storyline and personality, but the design (which is people's first impression of a character) wouldn't have been my own and other people could still buy the same sprite and use it in their own projects. Not to mention, if I ever wanted to make merch of the characters, that just wouldn't have been possible because the stock sprite design isn't mine.

That's why I decided to commission a new artist to make new designs for Oz, Arthur and Aslan. Carl and Fawna never had stock sprites to begin with, so their designs were never changed; they were just made from scratch.

While I'm aware that many people were disappointed with the change in art, I hope you understand and respect my reasons as well as respect the artist who worked super hard to make the art. 

It's completely fine to prefer the old art style over the new one; people have their own preferences and that's completely valid. What's not okay is constantly coming into my comments/social media spaces to harass me about it and/or call me names when I'm setting a boundary.

Oz's, Arthur's and Aslan's new designs are a whole lot more fitting to their personalities, their essence, their backgrounds and the story that I want to tell about them. If you find that you can absolutely not play the game because of this decision of mine, I kindly ask you to play a different game that is more attuned with what you're looking for.

I am incredibly grateful to those who have given me their support and kindness with the new release of Killer Trait. I've had immense joy watching everyone's playthroughs, seeing your comments and reactions. Thank you so much for your time. But unfortunately, the harassment has severely affected my mental health, therefore I wanted to clearly explain the importance of the creative choices I made. 

This will be the last time I will address this matter. 

Thank you for understanding.
