I had a very chill time playing your game and really enjoyed it - a really calm and wholesome experience and I think we need more of those. You really managed to let the player/me feel welcome in your little fishing heaven.
+ Awesome vibes
+ Great pixel art! I especially enjoyed the character walk and fishing animations - smooth rope and the bait pulling in felt really professional and satisfying. The changing tileset is awesome too. Great Harvest Moon vibes here.
+ Nice SFX and Music - although I thought the fast music while the fishing mini game is on was pushing me out of the relaxing vibes a little bit. Would have liked a more calm music in this part too.
- Not such a huge fan of the limited bagpack, or maybe change the feedback when the inventory is full. I was laughing when I saw the fish flying away and thought it was a funny bug haha.
- The UI could use some work - it took me a while to understand that your icons for the inventory, the fish journal and menu are part of the UI. They don't look like buttons.
I would love this in Co-Op! Congrats on the game - keep it up :)
