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
