A little sad that the music isn't looping! And you should've make the recipes less expensive, why not even free? Finding out the real recipes is the fun part of the game, and it is really well done with the annotation system, I loved the idea! So you don't need a "farm" aspect to the game where the player that did solve your puzzle continue to mindlessly do the same 3 recipes over and over, because we gain nothing out of that, no dopamine, nor further knowledge. (and clicking on the bottles isnt fun in itself :/) What would've be a good way to implement the recipes in a progressive way would've been that when you successfully send a drink 2 successive times, it is then replaced by an other drink to solve. That way, the player is always solving something!
Anyway, congrats for your entry, I had a good time playing it!
