The is a really creative concept! The alien guy is really cute :D I wish there was more to the disguising yourself aspect of it. The only way to get caught was either to be too slow or to run fast, but there was never any reason to run when making the coffee. Something like if the character had to sneakily run research back to the UFO without the people noticing. Also, when I went to far down the map the game like completely blacked out and softlocked. I liked how there was a small variety of different drinks people wanted so it wasn't just serving the same thing every time. Good job! :D
Also, just at tip for future game jams, I recommend posting a web build version for your games, as a lot of people don't want to go through the effort of downloading files to play a game, and won't end up rating/playing your games.
