Very nice game! The idea is cool and I like how you get hints from the customers :). I think the choice of the aliens could be a little smarter: not asking for desserts you already know (since the goal seems to be to learn all the recipes?) and asking for maybe just 3-4 different desserts each time, not too many different ones (so it's eazier to remember and focus on the new recipes). It's nice to have the timeline at the bottom though :)!

The music gets a bit repetitive, some sound effects could help too. I like how you wanted to put the player in a spot alien to them :) (as you wrote above) and I do think you were succesfull at it :D. Great job on the game!
