The first page lets you make only 1 cut, the second lets you make multiple cuts. I had to put a playfield on top of the "unit" (aka rectangle, which is in a gridded playfield) so that I could allow you to "clear the cuts" by simply using the Playfields "remove all" tile from the collections category, without removing my unit and having to put it back each time.

Nice!

> Next I am thinking about using polygons as my "units" so I can visually show the cut by duplicating the polygon and modifying the vertices to points where they intersect the cut. Then I will "animate the cut" by moving the polygon's apart. This should scale to multiple cuts without code changes (using the Playfield's "tell all contents" tile from the scripting category). Well at least I think it should testing and the mandatory debugging that occurs anytime I write code will tell ;)

That would be awesome! Seems quite challenging to implement ;)

Btw, my kids love the "Slice it!" game based on that idea:
