Hi Mayank, When the game starts the flame can only walk, you have to collect burnable objects to evolve and gain new abilities. The hand is basically a boss fight where you have to dodge it.
I did retry the game. It seems that the hand doesn’t move to the extreme sides in LV1, so able to dodge accordingly. Some intructions would be great btw.
P.S. - Forgot to mention but the opening cutscene goes well with the music!
