Hi! Thank you so much for the feedback! Once mixed 4 drinks, you gotta drag the tray to the desk above (it's a "top-down" view; what is above is the serving desk). Then, you can continue the game and talk with customers to unravel their stories!!
We tried to explain all the mechanics through the Boss dialogue! However, it's true that an in-game tutorial would have been pretty useful, but we didn't have enough time! Thank you for the feedback!
Ohhhh thank you for the kind words and the feedback! Our game designer would have appreciated more time to design the mechanics and game itself... We did our best!
