Invisible Ink is an unique puzzle game, where the goal is to watch the pen drawing in invisible ink then try to guess the shape. It has multiple difficulty levels and multiple languages to choose from. If you're stuck, a limited amount of hints are available (using them impacts the score though!)

I made this game a long time ago, in 2010, for Flash. In 2018, I've ported it to HTML5 using OpenFL (as the original was written in Haxe).

Hope you'll enjoy this one!
