great job!! I love the idea of circling the slime to kill it. The control mechanism is really good and easy to control comparing to other GTMK circling/looping mechanism. How about adding a huge slime and circle it to damage it. The slime then will shrink to smaller one depending on health points. In addition, how about also drawing/circling a specific simple pattern to generate magic or summon a creature to help us to attack the slimes?
