The Storm run puzzles to be reviewed without rating change, I believe this is being considered already.
As with regard to the interface, the difficult thing to get used to was the increment/decrement but it got better once I learnt how combos work.
lichess.org/page/stormTo know more about Puzzle Storm.
The button is at the bottom of the chess board in Storm window, 'About Puzzle Storm' and a little too small maybe.
The Storm interface is supposed to look and feel more gamey compared to the rest of Lichess, but yet maintains the simplicity and minimalism that Lichess prides in. So, I think it's better to give it some time, to get used to the layout.
Please note that the colour of the puzzles do not change within a Storm Run ie., if the first puzzle was White to Move, then the rest also will have White to move throughout. So no confusion with regard to the sides.
There was a lot of uproar over Lichess V2 design choices and the icons being too large, but I guess most critics were convinced in time.
So keep playing those Storms and bring to notice any problems you may encounter.
Cheers!
