I love the setting and the idea that every thing is coffee related. Game play mechanic is very neat as well! Definitely a spin on the usual "click and drag the ingredient" methods. Very inventive game design.
Could you consider making the fishing area a bit smaller though? Or perhaps more populated? A lot of the time I was stuck searching for the fish/s I needed for the next drink, so I think have a smaller area to search or more fish in general could be beneficial. Also having more fish could add extra challenge and more punishment if you accidentally hook the wrong fish.
The hook mechanic is great tho, again very inventive. I think it would be interesting if you could hook multiple fish at once, perhaps all the fish you need for one order. In doing so, this could add extra challenge or less time to reel in the fish, but I think it could be a good risk/reward mechanic.
And I get it's a game jam game so you may not revisit it, but those are just my thoughts. Overall you guys did a great job and the game is very nice looking, very good presentation. Keep up the great work!
