Nice game concept. Very clean implementation.
I love the sound design. Reminds me of Stardew Valley a lot!
Easy improvement suggestions:
- Add background music.
- Allow seeing a little bit further beneath the water while traveling in the boat.
Harder improvement suggestion:
The gameplay doesn't lend itself to much feeling of progression. While there are upgrades for sale and you must buy them to fish deeper, the core game loop isn't changed in any way. Once the player understands how to move, fish, and whether to click the Eat/Sell button, there is no new progression really offered that forces the player to learn something new, do something different, or reach a higher level of mastery. One way to add more progression might be to make the new fishing rod control differently... Or add some hazard or threat besides hunger.
Those are my thoughts. This is a very polished gameplay demo, and with some gameplay evolution, this could become a really cool and beloved game!
