Thank you for feedback!
The reson it doesnt charge when you are not holding anything is because when I tried to do it for some reason it was breaking the charge. So i was like, eh its a feature now. Im sure it doesnt make the game too hard. Well I quess it did make the game quite hard xD
I hope you know that you can attack with right click or space? During the time bar thats down is emptying ANY fish you touch will die, even shark (doesnt work on Fishing net). So you can kill multiple fishes with one attack. Its slow to charge back up but might save your day. Also you dont get points from killing.
Maybe the reason its not always responsive is because its a browser versio? I didnt have issues even on browser but obviously doesnt mean others wont. Did you have a lot of tabs on or anything that might slow it down? Or what browse did you use? Maybe some work better?
