[PC] [2010] The Black Brush game before 2010

I used to play this game a lot when I was a kid like around 2010-2013. Now I only vividly remember part of it.

From what I can recall :

• It's a PC game
• There is a black brush which u control using mouse to play
• U were like solving puzzles and there are also bosses (like chinese dragon (but like 2d)
• It has ancient chineset theme-esque to the game
• It has stages/ lvl
• this game I played along with flash games
• It's NOT Okami
