I think it could use a little more clarification on what you press for the Regular Clients because I tried pressing space when it showed the massage hands symbol and nothing happened or I was doing the wrong thing to them and got heart broken but when I clicked it worked. The tutorial shows a hand symbol, mouse with left click highlighted, a blank mouse, and an X and explains none of these properly. If that is a big part of gameplay the tutorial should really do a better job explaining it imo.
Edit:
You know what, maybe I'm dumb but I see it was saying to left click for the hand icon and it showed that with the mouse symbol lmao
I thought it was just a long sequence in the tutorial with multiple things going on. However, I could see others also making that mistake.
Another thing though, how long or how quickly you're supposed to click after they give you your instructions is really unclear and hard to time, I've got good rhythm but the starting note is very hard to identify.
Maybe for ease there could be an onscreen timer or metronome and maybe as you level up the timer only shows up until the first beat. I think that would help tremendously! Because if you are thrown off rhythm from the first queue then the rest will surely follow.
