Impressive Work!
Personally, I would not be able to bring myself to develop games in assembly xd but for a QR Game jam it's probably the best choice.

Very well compressed! 
I also love these games that make you think! So IMO it was also fun! I just had a very hard time grasping the goal at the beginning and the control. J, L seems like an odd choice to me (opposed to a and d  or <-,->). Also did not like the colors used that much. It's a preference thing I know but I feel like a better distinction between snake, black, and lights on could have been made.

Great stuff!

Thanks for the feedback!
For the sound  - I wasn't able to produce any meaningful/fitting music that doesn't nuke the 3kb limits.
I agree the gameplay is a bit lackluster and not well balanced - should have put more thought into that!
Regarding the file-size ; I wasn't entirely sure whether the compressed TAR archive has to fit into a QR code or the uncompressed files thus I had to remove all spaces since each takes away 3 bytes w/o compression.
The PNG file is both a mixture of Tiny-PNG and own compression so thanks for the compliment ;P

Thanks for the comment - Have you pressed R to start the game? Either way, I've added it as a control tip to the game. Also, I've added the QRCodes of the Tar archive as binary (directly converted the file) and base64 code.
