Cute graphics! the mechanic is simple but definitively it is a really enjoyable experience!
is relaxing to fish in this game and it causes expectation to see what are you going to fish next (perhaps the clickerfish) and yeah, i love to see that people from the jam knows each other and the colab doing things like these ^^
One thing i hadn't in count, you forgot the text from the "hook" upgrade, as a programmer i'm a huge fan of you cause you've put "lorem ipsum" while testing XD
