I really enjoyed your game. I didn't understand it at first because lazy me didn't check the controls, but after checking them I knew what to do and was rocking the game. The game wasn't too difficult and I generally didn't use the sprint key because I didn't need it and forgot about it most of the time. The sprint is a little too fast too. The enemy AI is very simple, but sufficient enough. If you plan to upgrad the game I would suggest giving the player more space to walk around and giving the enemies different behaviors because right now you have the typical run in a circle motion to avoid enemies.
I really liked the idea with the fishing rod, but the holding position of the fishing rod is a little weird because it is at an angle to the throwing direction which is very confusing. Maybe let it point to where the player is aiming and have a little animation when charging the throw and performing the throw.
