Yeah I'll be doing a new TAS. My goal is 10-11 minutes, maybe sub 10. I had TASed up to level 7 on the Japanese version but I'm starting again because it turns out that the English text is shorter!
The skip will probably look completely different and more optimized once I do the TAS, but this method is possible RTA. The only hard part is getting the pause glitch. To do it without losing any rounds its just a precise pause glitch after winning the first round. You should still get the text and Alex should be completely still during the second round.
Verified on console. This took so many attempts though.
It's really precise.
Heres the quickest RTA Janken castle skip I've found so far (unless someone wants to duck under that block while invisible). The second pause will be more like what KrazyRasmus was doing.
