I am trying to become a better developer and thus I am doing small projects to upgrade my game design skill. I want to make my UX feel better and not so dull and boring.
Right now this system feels soo finicky and generally it isn’t smooth at all.
What do you think I should add to make it better?
I think when you cast the rod maybe give a small delay before then I starts, because the animation is still playing and thus clips. Or if the animation is done and just does that, maybe make the rod in the animation go a little further down.
So when you first click, bar fills up, you release, I should give it like a small wait for the animation to finish and then make the animation finish exactly where the second animation starts?
Yes, I think if you add a small delay before the countdown starts it would feel much better. But it needs to be a tiny delay.
Consider trying different easing styles
Yeah tbh the animations do feel a bit too linear, too robotic I guess. I’ll try this out and report back, thanks 
First of all, the visuals look too simple. Look up some color palettes for your ui, And add some effects to your ui (i dont know if this is placeholder). make the countdown text anchor point {0.5, 0.5} because the ui scales from the upper left. this will make it scale from the middle, Maybe some gradients? A little touch of colour change may look cool (not sure this one). my idea is the closer to the target, it gets green, but if its going far its going to be red. Maybe different easing styles. And a little delay before the countdown, A water splash particle to where rod hits with :Emit() i dont know but you should add somethings to get attention of the player and have fun.
first of all, i see this is just a prototype so i wont judge for it being too simple
consider adding fov change (like -10 or sum), if countdown isn’t crucial i’d remove it because it removes all the dynamic in fishing, also make the slider thing you control more smooth, because the way it moves is too sharp, consider adding “UiCorner” to things if blocky style is not crucial, change easing style for the “|” thing, add text pop-up for the fish throwing (e.g if you hit green, shoot something like “Perfect!”, if its lower do “Good!”, “Bad!”, etc., also add more sections, for example red/orange/yellow/white or whatever color you think fits best for highest section when throwing a rod), that’s pretty much all i can say currently
quick upd: also remove score bar at the right when you already threw the rod
