Finally the new world update has arrived! I was hoping back then to push it out by March, but here we are where we are :) In any case, here's what was added:
Added World 7 with a bunch of new assets, 2 new enemy types and a boss (as per tradition)
Added Route system support to Worlds 3 and 4 (currently Route 1 only, system is still in early stages of development)
Further improved precision on some diagonal transitions (6th grade geometry is hard)
Minor improvement to World 6 "Now entering" card
