Aw, thank you for the super sweet and thoughtful feedback! This is extremely helpful and we're so thankful you took the time to playtest the game!
We'll definitely make it a priority to implement "recipe-fixing" into the gameplay loop, and add more visual indicators from the NPC on when a drink was correct vs. incorrect. An idea we had previously was a trash can to "restart" the drink, so we'll probably be implementing that going forwards.
The cat and the crow are there because the game is meant to be played with two people locally (think Fireboy and Watergirl!). We'll probably implement a main menu selection to choose between singleplayer and two-player later on, though, so people actually have the option!
Thank you again and we'll be revisiting this feedback often to improve the game :D
