Addictive as chocolate.
Excellently addictive, enough to keep me going for that final acheivement for another 15 days after I finished the rest. I finally managed it though! 6000 feet of distance... just. Brilliantly made, and a fantastic melt of skill and logic.
Brilliant.
Brilliant idea. Truly wonderful. That 3rd wave's hard D: The achievements are bloody clever too. I'll be playing this for a WHILE!
One of the best series on NG - by far.
The whole Spin series is just awesome, though at times insanely difficult to get your head around. It's a brilliant concept, and it works brilliantly.
Innovation at it's best
Wow, such innovation. The mix of photo and art is incredible. And some of the tiny differences where impossible to find without that hint, I swear. An incredible game, hope there's a 7.
No Knux?!? What's wrong with the world?
The designer was great, I loved it! But you said that we could make a perfect Knuckles. But I can't figure out how! I've made Tails, Sonic and a few of my own characters! Proper good fun!
