If I ever revisit this I'll make sure to add some more visual aids. Like right now there is no way to tell when a beat has passed and the health bar pulsing isn't super obvious. Also I just had another go at COTN to compare and the interaction time window seems way more forgiving there. RSU might actually be harder as far as timing is concerned, I did almost no testing on other people so far and I know the whole thing in and out by now, so I have now idea how difficult it really is. :D
