The goal of this category is to collect all of the flowers/crystals in the game. This involves unlocking all levels that contain flowers (everything except 5T), which requires 232 tetrahedra. Since there are 304 tetrahedra that can count towards the total, that means you can skip 72.

This run isn't bad for a first attempt to route the category. It could definitely be improved with no unintentional deaths, better movement, etc. It can also be improved with better routing in levels where I don't normally collect all the flowers in other categories (particularly 3-1, 3-8, 4-4 were bad this way). A better tetra route is also necessary - a few tetras that were not gotten were actually faster than some of the ones I did get, just that I hit the total that I needed sooner than expected to. More runs to come soon. :) ???
