I'm 3 months in, pretty good so far but a few interface annoyances:

• You can only full-screen from the main menu, so now I'm stuck playing in a small screen after minimizing to check another tab.
• You don't actually use Enter like the tutorial said, the drink is entered automatically when you input 3 ingredients, so you can't cancel if you got the last one wrong.
• Can't use the keypad numbers :(

Edit: Just beat the game and sheesh it's tough. Really liked the story and theme, the gameplay made me feel helpless (call it a feature) and the snippets between levels are funny.
