I liked this one its simple style didn't take away from the experience. The fish made sense but not falling from the sky unless maybe a mumma wyvern was throwing them in the air. The main part I would look to refine would be the fight at the end as you can just click attack each time and doesn't have much more there maybe an mini game to dodge incoming attacks?
Either way I did really enjoy it for what it was and enjoyed your story - good job :)
