Played all of Week 1 in portrait at phone size. Fair warning: a script drove the touch input for me, at roughly 10 FPS on software rendering, so my releases land late.
The guided practice is the best tutorial I have played in this jam - it pauses the pour exactly at the target, so it cannot be failed, and the Reference / Batch inspection side by side teaches the whole loop with almost no text.
Scored shift: 10 1/2 out of 20, and three of my four orders came back "too much potion", never too little. There seems to be a floor on a pour: drag a pigment over the mixer and release instantly, with no hold at all, and the mixer already reads 25 / 100 mL. 150 ms of hold only adds 2 mL more. Order 03 asked for 13 mL and I delivered 30.0. Ramping the flow up over the first second, or letting the product vial stop at the ordered amount the way the lesson stops the mixer, would fix it.
Beautiful object - the glass and the liquids look expensive.
