This is such an amazing game, especially done in such a short time.
You paid attention to every little detail and the game seems to be made with such love, I am so impressed. This is exactly my type of game- I didn't imagine that anybody could pull something like this off in such a short time!
The controls are intuitive, and while I did need a few tries to understand how to fish, it soon became easy enough to not get frustrated (unlike in other games with fishing -_-)
I really liked your characters and the whole idea of having a plot on why you have to clean the river. Art and music were obviously really well done and fit perfectly into the vibe.
I really enjoyed it, good job!
