The music getting faster put on the pressure! Luckily I managed to beat in on the first go so I won't have to watch whatever fate lied beyond the timer.
I found the jump / moving forward a bit inconsistent, and I I didn't realise I had to full screen to see the UI lol. Maybe you could adjust the viewport settings in your itch project? Also you mentioned in the description seeing the screen shots, but to get them to show on your project you need to click edit theme then edit it in the layout section. I only know cause I had the exact same issue (unless these issues are related to my device default settings, in which case sorry for this).
Besides that though, the sweep resetting after each stop and jump made it intuitive to maneuver, and I think it was a very well chosen difficulty. Great job, was genuinely fun to play!
