thanks for the feedback, it will help me a lot :)
To answer your questions:
1] Since this game was made using free assets and since I am very bad at animating those were the only available animations lol
2] The person who stole the rock was an expert on the witch and studied it for years. He knew about how terrifying the witch was and its powers. The witch killed the man who stole the rock before he could return it. Basically, he was selfish and cared more about his research. He left the note because he knew his actions would come back and haunt him. Since the main character was in the richer district of the city the witch didn't notice him. (I don't know if this is kinda lazy..sorry lol)
