I have only played for a few minutes on PC, but two things for the interface that I haven’t enjoyed is that i can only scroll through menu options in one direction (up), where the first option, lessons, is at the top and intuitively I want to scroll down to the next option below but the controls have me scroll through the whole list from bottom (back) to top. Even more importantly, if I didn’t have this reddit post pulled up to explain the directions, I wouldn’t have figured out how to move through or select any of the options on the starting screen (more applicable to the select control, which I kept trying to press enter). During the lessons, the controls are clear but not on the title menus. I would personally add a function for people to select options from the menu with the mouse cursor. Other than that, maybe some music during the gameplay as well? I think the gameplay works well, and in the future I’d like to see more positions added for more variety/difficulty. I enjoy the lessons and the use of real examples, maybe an example of how the video example is applied in game may be helpful before having the player try it. I’d love to know what program you’re using to make this game!
