I have only just completed this game (think I finished on Monday/Tuesday)
Another great Sonic game to me
smile I liked the gem custom power ups that Sonic had (only have about half of them) but I had no idea how to use them when I got them first (looked it up on internet)
Loading screens were the only bad point about the game
You get a mission loading screen
told a little about it loading screen
Fail Loading screen
annoying comment Loading screen
repeat till your done
i had that about 5 times on the test of courage for sonic (you need to fight without any rings against a load of enemies)
I managed it after i knew how to use the red gem (slows down time for all but sonic)
Annoying parts that i got stuck on:
Sonic:
At about 40% in the volcano place with knuckles
Test of courage
Saving the train 3rd switch as I had about 3 seconds to defeat the enemy first time on my last life then i got stuck on the box by the switch
Some of the speed sonic parts as you could jump then go flying off the level
Shadow:
7% no idea where to go to next level of it
Not many other problems really with Shadow
Silver:
None First episode I completed (Sonic was still at 40% and Shadow at 7% when i finished this one)
Last Episode:
End of the world was a little hard with the purple things that killed you if they touched you and one kept getting me on Silvers part when you had to stand on a small ledge with sinking sand on one side and the part you climbed up on another (got drawn into the sand about 4 lives)
Game rating
8.5/10 (loading screen amount dragged it down from 9.5)
