Simmetri interactive tutorials are probably the best i've ever walked through! Fun, nicely constructed and well-rounded for quick intro. Hundreds of time i've heard word ''gamification", first time i see somebody have properly implemented it in software learning curve.

Just wanted to say big thanks to developers!
