Fun, but challenging – Lightbot : Programming Puzzles Review

Very fun to walk through. I just learned some prog lang during eng school(c,matlab,vhdl) and wanted to practice progr logic. Light-bot is fun to use and at the last stage- very challenging! Needs a walk through somewhere to help but I guess that wouldn't teach anything... Only real complaint is once I beat the last few stages left what's left to do that's as fun as before?!? (I don't want it to end!)
