So far this game is really fun! But, I would say that after green hill zone, everything gets way more challenging and less loop dee looping and speed running the levels. Green hill zone I think is the only easy and less frustrating zone. After green hill zones the game actually requires you to stay on your toes more than you have to do on the first zone. And more concentration is put into the game. I would say I died a lot. But Im giving this a 4/5. :D
