Original Alto was much better. Alto Odyssey is just nowhere near as consciously or intuitively built. Odyssey tends to prompt you to intuitively do things that will force you to fail. Sometimes the ground on the other side of chasms is too far or too high to reach even if you complete the chasm jump the way they want you to. You have basically no control on wall rides. Often goals are based upon settings that may not pass after a really long time. There's just no room to improve with practice.
