Hello,
I played through the whole game and I can just say WOW. This game was a very nice fleshed out piece of art.
The mechanics:
I liked the fishing - it was designed very well. It had everything - boundaries to keep you updgrading and wanting to see whats below; upgrades that were very cool and meaningfull. The gameloop didn't get boring because the upgrades weren't to far apart. There were lots of fish and diffrent types of collectibles.
The art:
You have a very nice and neat pixel art style. The fish were very detailed and the background was interesting. I really liked all the animations because they had some nice cartoony vibe.
The story:
First it was a nice addition to add story to the game because it added a lot of character and I didn't anticipate the the ending. The notes were interesting and I enjoyed finding them and reading them ( I liked the hidden red letters).
Overall this game has the potential to be top 10 even top 5 in this game jam. This was an incredible experience and an awesome game.
Cheers!
