Reminds me of when I used to be a barista, the customers always did act like the world would end if they didn't get their coffee! The game was very short but extremely well put together. All the little dinosaur designs, the detail on all of the props, and the meteor slowly approaching in the distance showing how much time you got left!

I think the audio gets a bit loud at the end, but I assume that was the intention since its basically acting as your time limit. I also managed to get the bug with only sugar, but only if it was the last ingredient I used. So I ended up just developing a habit of doing sugar first, then coffee and/or milk, then cocoa. It seemed to help avoid anything bugging out for me. My final total was 9 Joyously Perfect Coffees! 

I like the humor of your game. The asteroid impact is well done, including the signaling before it hits. Would have been nice to to serve some more customers before everything explodes.

I think the sugar/cocoa bug also appears in other situations. I was using them after I filled the mug with coffee, which let it freeze as well.

One hint about fullscreen: When you remove the fullscreen option in the itch settings (you can do that also after you published the entry), it is easier to hit the Godot fullscreen button. The itch fullscreen button is kind of broken and covers the blue Godot button, which is doing what one would expect.

The asteroid sound effect slowly rising in the background was well done.

I think there is a bug where you can't pick up the mug after you use the suger (salt?).

The death screen was very funny.
