I finally found the game, it's Gestalt_OS https://www.increpare.com/game/gestalt_os.html Hello, I played a puzzle game somewhat 4 years ago, but I don't remember the name. The game is about placing symbols on a grid to get to a specific solution. Each symbols has a functionality, like copying other symbols, or move them, but the functionality is not described, we have to guess what it is. IIRC 40 (it is 50 actually) challenges to solve, and the game is a game playable on online browser. Do you guys know what it this game's name?
Is it https://krackocloud.itch.io/gridspech?
Ok, thanks to your link, and searching related games, I found it : https://games.increpare.com/Gestalt_OS/
Might want to update your other post too.
Thanks, but it's not this game. The visual style is pixelated, and blue purple colors.
Do you remember where you played it?
It sounds/looks a little like some of the stuff from bontegames.
