Decryption of png, how?

[Google]

Trying to decrypt a png file, the header of my png starts like this:

Code:

40 53 23 54 24 4f 25 53 6b 00 00 02 04 e9 bd d1
f4 b7 f1 85 63 b6 53 b4 ab 40 f2 58 47 9a af 2a
a9 83 94 aa 69 f7 6f 04 18 b6 d2 ba 83 1a 1e ac
cd 9f 45 28 47 c2 55 f0 5b 9d 53 ea b1 44 85 36

I tried different codes and decryption algorithms but to no luck. Does anyone have a clue? I'll attach the file below (and another one, if you can compare or see any differences, not sure if that will help though but both seem to be encrypted)


Here is a link to both the encrypted images:

Noticed, every png in the game asset starts with this header:

Hello!
I have some files of the same format (don't know if that's the same game)

The game these files are from is called 寻光之旅 and made in Cocos2d
