Puzzles and idea are very clever! I really love this mechanic!
With a few more screens and maybe other puzzles it will be way more challenging!
Hope you will continue to develop this(ese) game(s), the idea is stunning.
Maybe using a shared save instead of codes (you have to do it instead of checking a walk through) would be interesting.
We thought about this, however we wanted to focus on game and ideas, not really techniques. I think the best way to have games working at the same time would be to have them connected over localhost with TCP/IP, but that might've been a bit too shady (firewalls and stuff). Shared save would be nice but not really knowing how saving data in browser works (different domains probably would break it), we didn't want to go that way. I am actually very glad that it worked out the "analogue" way.
Cheers, glad You liked the game.
I agree, asking the player to install and run a local server on this computer seems a bit odd for a game jam project. I think you can achieve it with cookie in a pretty simple way but I understand that learning all of that plus making a game is a bit too much to handle for a game jam ;)
It works pretty well actually, I was at first pretty surprised by the concept and how it will works. But I think with a little "developer magic" this prototype can really be an interesting project.
