Thank you for your feedback.
When I considered how shapes would appear, I wanted to keep it simple by keeping everything in a row.
There’s been a lot of good feedback about the timing of the notes. I think it would have been good to make it more obvious when to morph (when the shapes are directly overlapping), changing the sensitivity of the scoring would have helped but I think it’s also possible that some of the shape changes may be slightly off time.
There is mapping between the order of the shapes on the keyboard and the logo of the game (the shapes actually resemble the letters in MAX somewhat) but I think it would have been better to make it more obvious to the player.
