How to Clip : Ground Pound, then Press XYA at the samish time. PRACTICE!!!! IS KEY for sphynx clip, hold left after clip

"Same-ish" implies an order. What's the order of the button presses? I do appreciate, however that you have noted the holding left bit. I didn't know that. Does that prevent you from going straight into the sphinx room?

Same-ish as in close together but doesn't really matter if they're not at the exact same time. I think as long as you push one of the cap buttons before the jump button, you should be good.

I put my thumb in the middle of the ABXY 4 buttons
