Thank you so much for taking the time to leave such detailed feedback!
I'm really glad to hear you enjoyed the game and its visual style, even though it's still currently in development.
I'm taking note of every detail you mentioned—from the input timing adjustments to the UI bugs and the stage progression clarity—so I can include these fixes in the update I'll be releasing later this week.
Also, I'd like to invite you to join our Discord server so we can chat in more detail about these and other aspects of the game. Hope to see you there!
