Hint for Digital Cryptography 04?

[Eraser]

This is the last non-challenge puzzle for me and I'm stuck. Can anyone give me a hint?

It's obvious that the message is hidden in the least-significant (last) bits.

I've already tried the following. None of these worked:

1. Interpreting the bits as ASCII (results in the letters PG but this is not accepted).
2. The same as number 1, but following different directions or patterns.
3. Grouping the bits in groups of 4 or 5 and using the code A=1 Z=26 or A=0 Z=25.

[the Seal of Approval]

Okay, so you most likely already got this, but I think the puzzle is kinda bullhonkey (or really clever. But a few hints:
The pixel art will be 4x4, not 8x8 or 16x4
The points you need to focus are split in two. Notice that the binary code is split into an "AAAAAAAB" format
Not that I kinda understand it is a REALLY good late game puzzle that brings it all back to the first chamber
