I love the surgery game show concept, and the mechanic of spinning the scalpel to perform operations is really creative.
Although, I was a little confused about the objective...was I supposed to cut along the dashed lines exactly, or cut around and remove the target area?
I think the delay in controlling the scalpel could work really well if the goal were to follow the dashed lines precisely. Would be simple and to the point.
Nonetheless, I really enjoyed the idea, and I can tell a lot of effort went into making this. Great submission!
