Thank you!
The character model is not made by me (you can find it on sketchfab), I just downloaded the model and auto-rigged it on Mixamo for my college project. Also, the character controller is a free asset pack on the Unity Asset Store found here:
However, the ruins and images were created by me.
I am very happy that you understood the intention behind the mural as I wanted to create a narrative experience without the use of dialogue.
I will remember your feedback for if I decide to come back to modify this game.
Currently, I do not have any plans to expand on this game as I am currently studying and do not have much time to delve back into previous work.
