Hello everyone! I'm Wei. I didn’t expect to receive so much feedback from passionate players so soon after the release!
I’ve made some quick adjustments and also listed the planned changes for the next update.

0.1.1 Update Details:

• "GOOD" judgments no longer reduce HP
• The result screen will now wait for the Enter key before proceeding (to make taking screenshots easier)
• Made long-hold note colors darker

Planned Updates:

• Option to toggle track separation lines
• Adjustable explosion effect size
• Increased maximum note speed
• Customizable display options for call-out text
• Tutorial will be shown if no songs have been cleared
• Adjustable display options for HP and score bars
• Menu navigation with keyboard arrow keys (↑↓) and Enter key

Thank you all for playing!
