Seems cool, and the motion controls and surprisingly precise & difficulty honestly. You really need a steady hand. I personally don’t mind something with a steep learning curve, but maybe offering an “easy” mode where the controls are dialed down a little in intensity would make sense? I like the UI choice where the play field gets smaller as time elapses, giving a sense of urgency. I also like the “double hits” and “wall hits” concept. Some refinement in the scoring system to account for those would make sense. Meaning, right now it seems to be what “level” you achieved with the minor details underneath. Maybe work out a scoring system that accounts for highest level, double hits, wall hits, etc… and calculates and actual “high score” based off that?

Controls feel reversed for me.

I would add this as a setting.
