Any% TAS Route
SUNRISE SPRING
Sunny Villa
Enemy proxy off first rhynoc as RTA does.
Seashell Shore
Due to the TAS-only SiA method, it should be better for TAS to do this level second, and CS fourth. It may be possible to proxy off a shovel rhynoc to reach the EoL faster.
Molten Crater
It may be possible to proxy over the high wall in the first outdoor area, but IDK, haven't tested.
Cloud Spires
Hyperglide, obviously.
Sheila's Alp
Use either TAS-only SiA or current RTA method, whichever is faster, to enter this level. Run through it as normal.
MIDDAY GARDENS
Enchanted Towers
Use regular level skip, obviously.
Bamboo Terrace
Use under-the-bridge SiA to enter this level. Proxy off the first firework rhynoc as 117 TAS does.
Spooky Swamp
Proxying off the first gator should be enough to reach the high ledge with the miniworld portals, then on to the EoL.
Byrd's Base
OoB glide in, complete level as normal.
Icy Peak
I happen to know that it's possible to wall-glide past the first ice wall without destroying it first.
EVENING LAKE
Bentley's Outpost
OoB glide in, complete level as normal.
Frozen Altars
Enemy proxy off the baby elephant as RTA does.
Fireworks Factory
Use firefly proxy at beginning.
Lost Fleet
It should be more efficient to take damage for the Zombie at each acid stream, rather than all at once near the end.
Charmed Ridge
Proxy off the second crossbow rhynoc (or first cat wizard if that's possible) to reach the end.
Midnight Mountain
Get perfect helmet proxy, glide into the loadzone.
tl;dr: Different level order in Sunrise, get proxies wherever possible, general TAS strats here and there.
