It looks pretty cool, and I like to imagine that a good player could pull some smooth moves. I am not that player...! Shot leading is very hard, especially when the angles matter, and especially when same shot hitting the wrong target can kill you. I also quickly get overrun by other enemies when a centipede (or more) shows up, and I also barely get to practice against it so I haven't beat a single one, while the spiders are trivial.
There's a cool idea here though. Encounter design in twinsticks can be pretty boring, so making sure your shots need to count is a good step, and it plays into the fantasy of like, cool card-throwing edgelords. It's just kinda micromanagey and punishing right now though, and i'm not sure the dice are helping.
