Wow okay, this was a lot more than I was expecting! At first I was ready to drop the game. Was confused by the basket system, thought I was pressing the wrong button and accidentally opening the shop. Once I understood what was going on though, the fun appeared!
Love the idea that most of the shop items are technically optional. Every purchase feels like progress and you can get pretty "strong" once you get a basket upgrade and the doubled sale prices. I was also very surprised by the inclusion of a little animated end cutscene! Feels like y'all set up my expectations with the gameplay and story, and when I collected the crystal ball I thought "did I finish the game? what does getting the crystal ball do?" and it turned into a nice little sequence.
For constructive feedback, I think it'd be good to have some audiovisual feedback to indicate that you're returning to the shop automatically because the basket is full. Would help tutorialize the game much more naturally. Also, I had 4 cursed items and found one in the shop...? But after purchasing, it didn't seem to count towards buying the crystal ball. I decided to do more fishing and hoped it would cause the store to refresh. I found another cursed item while I was fishing, so I technically ended the game with 6 cursed item (the UI only showed 5).
That's all I've got. Fun little game! Good job team :)
