Questions about gameplay

[赌弄特四阿甘]

Im a new player of this game and i like these roguelike games very much. However, the aim bar and focus of this game gives me a bad feeling. When me and my friend enter the boss fight, our aim bar will disappear and we can only aim the point by feeling and the bar will suddenly appear some where i do not know. ALSO! the focus of this game make me headache. the focus cannot lock on your champion but the whole room. Therefore when we head to another room from the old one, the focus made a big move and this make me feel dizzy and crazy because of the sudden change of my focus. LAST, i hope the " option " can make us change our keyboard key of this game (the shift key is skill always make me hard to press it lol)

Thats all, and thanks for any reply! I will keep playing this game and hope these feedbacks can help this game better
