Thanks for playing! Yea, definitely on the confusing side, and more visual feedback and tutorials may lessen the confusion.
Character does starts from the red arrow, and any 4th beat will move your character by 1 square from the arrow, unless there is a bug where it didn't, I might need to look into it if so.
Edit: Yep, there was a bug. Turns out I was testing with different FPS to test delta value and didn't switch back and test the original value, so the character was faster than she should've been
