I already LOVE the new course elements. Can't wait to make more open-world levels(currently working on one) and boss battles that are easier to create. Gonna include Skewers in the rest of my castle levels, dunno about the other themes tho.
Super Expert's gonna take out some annoying levels in Expert, which hopefully I can beat more times now. The map music and background have neat details, with it being in space and spiced up music.
Looking at points of failure were also a helpful addition, I have a lot of sub-areas and the level select's mini failure points is limited.
