It seems like this can’t be fixed for now — sorry X(.
Please try your best to hit everything perfectly somehow

ahhh ok, thanks for checking it out :)

Regarding the charge issue, it seems that if you make a mistake at a charge section, unintended behavior can occur at the next charge section. This doesn’t appear to be limited to this chart — it seems to happen in other charts as well.

For example, a set of five enemies is supposed to trigger one charge, but sometimes the charge happens after just the third enemy, or in some cases, the charge doesn’t trigger at all even when all notes are hit correctly.

The issue with charges not registering correctly seems to occur when mistakes are made at the charge points, causing the charge to either not register or the timing to be off. It might be an issue with the game itself, but I will try to improve it as much as possible.

Thank you for the report. I hadn't noticed that, sorry about it.
I've fixed the issue.

This is on the hard track btw, I haven't checked medium yet

There's an issue with the line of charges in the second verse where even if you hit them all correctly, some of them don't get collected or charge your timer back up when you have your special turned on already.
