Liked it, although I was kinda confused on inputs, something gain focus and pressing space and mouse got me some weird stuff. I loved the light beam to persist after hitting the wrong spot, and liked the level stars too! Found kinda hard to hit the angle you wished for as already stated but that's not so easy to achieve, unless you have enough time or played with something similar in the past. Great entry! I'll came back for sure if you are going to update the game after the jam end
p.s: even if music can be distracting sometime I would recommend to add a little base to keep players playing to the rhythm :)
