Entertaining
I was impressed by the quality of this little game.
That's just another avoidal game, but there are some elements that make it different.
The graphism are pretty cool, the boxes, the hand, the witches, everything is coherent and suit well to the background. The overall is nicely backed by the dark music. And it is cool both to avoid and target in the same time.
Thought there is one defect in my mind which spoil this minigame a bit. So here is my complaint : there is no increasment of difficulty. I noticed that each time you "click in a box" (sorry, that makes me think about some song, he he), a witch is spawned. That's a good idea, but that keeps being the same until you die. Maybe, you could spawn 2 witches by box from the 50th. Or make the mana fill up more slowly. Or spawn witches independently from clicking on the box, to prevent you from waiting in a corner that your mana refilled up to kill all the ennemies.
I guess a work on difficulty would make this game more attractive.
(Sorry for my english, i hope you got me)
