Well made, I like this game's core idea! I think I would add more strategic fun to this game. For example, if players can see what's coming next, then they'd be able to plan out their next movement to be better like Tetris. Also if ingredients were limited (per day maybe) it would require more strategy and players can feel good looking at the huge invoices piled up after a busy day.
Enjoyed feeding these eternally hungry customers, keep going! (Susan must've gone crazy because of those naggy customers, poor Susan D:)
