Nice simple cozy game, though took me awhile to unlock all the flowers, plus sometimes I could not triger the flowers weather I pressed repeatedly or on the beat, I hink there's issue with your rhythm sync system or maybe the radius to detect button press is not configured porperly or there was something invisible in front of the ui that prevented it from receiving mouse button press which is a common problem with ui elements.
P.S ,thanks for playing my game, I have uploaded a new build for my game minus the bugs and plus some new collectibles, pleas check it out.
