Thank you for your feedback! We didn't have enough time to polish the game and make a tutorial but you are completely right! About the lose condition: every time a "customer" with a bomb approaches an oven, everything blows up and the game is over. Sometime we also experienced random blow up but we didn't have time to investigate the issue since it was rare. Basically you need to shoot down "customers" with bomb while serving normal customers to gain points :)
