On, the HD, pressing the end key would not exit the game. What i did was to either exit it or to soft reset. Either of which is rather frustrating. But i guess it'll have to suffice for now.
By the way, thanks for clarifying the "sphere" location where we press. However when do we press it? I've notice the the notes disappear before they reach the "sphere" so do we press when the notes reaches the curvy horizontal lines? As for the icon, i tried making it and its 64x64, i replaced the icon in your .exe file and for some reason it didn't work, so i'll guess i'll go try again some time soon. Also, what timezone are you guys in so i'll know approximately when to check this thread for updates.
same for me
