Hello, yes this is the correct game! basically, we went with a very vibrant theme for the normal overworld with an all "Greyscale" theme for when you are are inside the portals and fighting. You will need to find the portal and enter it to see the black and white aesthetics.
We ended up not having enough time to work on level design and a few other features we wanted. we have a lot of concept art and features laid out and fully planned with a few other potential concepts on the cutting board that are going to make this game 10 fold better. Stay tuned for future updates as we do plan on fully finishing this! :)
