Super cute art style and love the concept!! Your spritework is fantastic, which is why I wish I could see the fish that was caught for a little longer before the cat puts it away? Maybe there's some way to have it fade out instead of immediately disappear?
Only other thing might be a skill issue but I found the hitboxes for grabbing a fish to be a little inconsistent. Sometimes I would totally think I got the fish and then completely whiff, and other times I was super surprised and felt lucky that I was in range. Potentially a little circle highlighting player ranger at the base of the cat sprite could fix this? But ultimately I found it to be pretty fair and fun!
