Congrats, there's a lot going on here. A rare combination of rust and go code!
On my first play through I didn't notice the "type your name" part of the leaderboard screen and didn't end up submitting the score. It took a couple back-and-forths between the game and directions on the itch page before I actually figured out what on earth was going on. I wish there was a bit more feedback in-game to distinguish clock-setting and clock-winding, and to indicate when a clock is "set enough."
