This was an interesting play! I like the idea of a first-person brick-breaker type game, although I guess this is more of a guessing game the idea is still novel.
I had some trouble aiming the balls sometimes so it might have been nice to have forgiveness for missed shots, plus I think a reticle or something like that would help dial in some of the shots.
I misunderstood the goal at first (and simply tried to break all the blocks), so I wonder if it might have been helpful to show an example first (maybe by coloring the bricks for the first round to show the target, or something).
Pretty unique concept, not sure I’ve ever played a game like this with binary search before! I wonder if you could turn it into some kind of memory game…
