I think this needs something dynamic, here a few ideas:
* push the milk / coffee lever manually until your container is full, overfill could happen and you'd have to stay engaged with the game * drag your containers to places instead of selecting them and picking where to put them. * have more galaxy: alien guests, alien drinks, or even multiple ways (languages) they ask for the same drinks.
Good job anyway!
I really liked this concept, and overall the graphics, music, and sound effects were very nice! The angry manager was also funny. However, I think this game really needs some kind of tutorial or more detailed instructions - I'm not a barista or coffee drinker, and I had no idea how to make any of the recipes even with the recipe guide. I still had a lot of fun though, great work!
