Alright, thank you for the feedback!
I feared that my last minute written explanation on the gameplay would not be enough :) haha. I think all this is totally due to the fact that i've seen too complicated and the gameplay is not as wrapped up as it should be.
There is in fact no death or clear win condition :(, the game loops back to the start when all enemies have left the area with an item or disappeared because of the time.
About the controls
The character can indeed move by clicking/touching the screen, but not when the skill is activated (big red eyes). When the skill is activated, all the elements inside the circle area around the character are "paused" and can be moved around by drag and drop. Everything else outside of it when activated continue to behave as usual. The area of effect grows with time.
