Shapez 2 is a very worthy sequel, IMO. Adding logistics beyond conveyor belts is quite nice, and 3 levels of height give quite a bit more options when building. You do often benefit from a build staying at one level since it makes platform blueprints that consume 12n belts of input to make 12 belts of output quite a bit easier, but several buildings are intentionally impossible to do that with for challenge.
The difficulty levels are also pretty well done - I got some fun learning moments out of Insane in particular. Hexagonal mode is also interesting.
The use of “alumni” in the singular. A person is an alumnus or an alumna, the alumni are always a group. Seems to be a very American usage, and I don’t know why it feels aggravating where other Americanisms like positive anymore don’t.
