This is so cute! The art and the music are amazing, really fits the vibe of the game. I'm really digging the funky almost jazzy track that plays when you're on the fishing screen. It might just be me but jazzy piano tracks always fit water-based levels.
Just some points for improvement, as Pea already commented I feel the UI is not as intuitive. It took me awhile to figure out that you had to press the buttons below the sushi to change the variants so you could serve it to people, maybe making it clearer in the tutorial or reworking it would help?
Overall, great work guys! I saw that this is a lot of yall's first jam and you really made an amazing product worth showing off, especially considering the time constraints. :) Looking forward to what y'all have in store next!
