PiCross
The thing is... I wanted to make a PiCross game that works easy, because the ones I found online wasn't exactly that.
The roadmap includes a digitalocean instance, some work on the styles, and being able to play maps bigger than 5x5 (the logic is the same, but, you now, I may have hardcoded the 5's somewhere...).
Instalation
Clone the repo, open your favorite browser (firefox cough cough), and open the index.html file. Voila!
Instructions
Click on a square to mark it as valid, or shift-click on a square to mark it as not valid
Future enchancements
Drag to paint different squares with the same click. Put some style on it (for god's sake).
