Hello there :D
First of all, thanks a lot for your feedback, we are really happy that someone liked the game. If you couldn't end a game it may be because fishing time never ends!! We wanted to make a simple game, but we also didn't have much time to add gameplay mechanics. As you point out, we mainly focused on the 3d-art (first time for us ^^). About the music, we curated some music and sound royalty-free libraries to make the final selection and it seems it worked out pretty good :)
Cheers.
