More than 1 year ago, I created the QR Code JavaScript jam, and I promised I would create a second one...

So here is the second QR Code Jam, this time with any programming language!

You are allowed to do any compression necessary to make a game that can fit into a QR code; though, this phrase has different meanings in different types of programming languages:

- Compiled languages (C, C++, Rust, etc.): The compiled game's executable (Both in Windows's EXE format and Linux's ELF format) must fit into a QR Code.

- Interpreted languages (Python, Lua, etc.): The source code of the game must fit into a QR code.

- Bytecode Languages (Java, LuaJIT(?), etc.): The bytecode of the game must fit into a QR code.

Rules and FAQ

• No NSFW.
• No writing the code of the game itself before the jam starts.
• When uploading, you have to upload an image of the QR code of the game along with the source code.
• You can upload more than one game, but please focus on quality more than quantity.
• You can use any engine/library/whatever you want.
• Assets (images, music, sound effects, etc.) do count towards the size limit and need to be made during the jam.
• Have fun!

Clauses

To avoid confusion, I created some "clauses" (idk if this is the right term):

- The Multiple Files clause:

When using an interpreted language, all of the game's files must be concatenated into one file or put in a TAR archive.

- The Engine clause:

The code of any engine/library/anything else except the core game used doesn't need to be included in the QR code.

- The ELF clause:

If you're using Windows, there is no easy way (at least that I know of) to compile a game for Linux's ELF format, so you have 2 options:

1. Upload the source code along with your game (with a Makefile or/and build instructions) so I can compile it.
2. Avoid making a Linux version of the game entirely.

If you have only Linux... you need to use an interpreted or bytecode language or compile the game yourself in Windows (or just not make a Windows version).

If you're using an interpreted or bytecode language, you can just make the game and not have to worry about compatibility issues with Windows/Linux.

Rating criteria

• Compactness: How well the game fits into a QR code.
• Fun: How fun/addicting your game is to play.
• Art: How well drawn the graphics of your game are.
• Music: How good is your game's music.
• Gameplay: How advanced your game's mechanics are.
• Overall: Self-explanatory.
