Very polished game!! And 30 levels is a huge amount! I played all of them, although I maybe cheated in some of them. Some of the levels were super easy and some required some thinking. As the movement wasn't grid based it was possible to go between some fire-activators. Also I think the camera was sometimes too far away and it was hard to do accurate movements. It was stressful when the fire dudes just ran into seemingly random directions, I just tried to avoid them altogether
Very good job, fit the theme well.
