Forget zodiac signs 34,

34

I can list most of these
Top Left: Bloodbath, (as depicted) 99% triple spike
Bottom Middle: Clubstep, first monster i believe
Middle Right: ReTraY (i think that’s how it’s spelled?), but isn’t that an easier?
Bottom Near Right: Back On Track, again, another easier
Bottom Far Right: Referring to Tidal Wave
Middle Near Right: Referring to Bloodbath
Bottom Near Left: That one level with the “impossible timing” coin
And yeah I’m not sure about the rest

Moderates can I is congregation

Above it is the infamous devil vortex saws

I actually might know why they added these saws
When the creator completed the level, it was secretly auto, and when he revealed the object count, it would be different from the non-auto actual version, so the just added random saws to add more to the object count
