Exactly what I was worried about. But I gave the game another go and was trying to think about this and for the double spike wall bounces, I was also switching the movement direction mid-air, not only the scale orientation. Like I was actively trying to move towards the second set of spikes after the first bounce. And with the proposed controls scheme, that would mean that the scale position would switch as well with the character movement after the first bounce.
Anyway, after playing the game for a second day, I feel like I started getting used to the controls. Still a bit unnatural for me, but I could get there eventually perhaps.
