I can't recommend the game. It breaks it's own rules to make it much more confusing to make shapes. It comes down to how cutters and stackers work, and the tiny mechanic they differ on. The stacker will change the shape's layers if it can stack without conflict with another shape on that layer. The cutter makes no layer changes even when there is no conflict thereby allowing shapes in unsupported layers to magically float after being cut from their supports.
Furthermore, I disliked the way the game shows the different layers; it just shrinks the shape the higher up you are in the layers. Having to stop and squint my eyes to compare shapes to figure out what layer the shape is on does not work well for me. A numerical way or something more to dissect a shape and it's layers for info would be nice.
It was fun at the start but I dislike when games depart from base mechanics in their quest to make it harder.

Fun

very very fun :3
