So nice to see another chill game for this jam. I'm glad you learnt a lot from doing this game jam. The game looks quite nice. I particularly liked the abstract look of the sunset and sea. But I think the storm cloud could be improved. The rain and fishing sound effects were good, but I couldn't clearly make out any sounds of thunder. Some relaxing music would also help with the chill vibe.
There seemed to be some clipping issues.
A small issue is with the controls. You shouldn't use tab and escape for browser games. Tab breaks webpage navigation and escape just releases the mouse cursor.
It's definitely a nice start and impressive for a first jam. Well done!
