TAS vs RTA
Only the clam zip in World 3 is doable in terms of glitches... the world 3 fish zip and the world 4 goku zip was apparently difficult to achieve under TAS conditions, nevermind RTA.
I wasn't able to replicate either when the TAS was being made, but was able to replicate TAS Clam Zip a couple times in the first 10 or 15 minutes of trying.
Struggle to achieve with the TAS must be almost impossible in RTA :O
Thanks for the reply Sean!
