How many zones are in this game?
12. Kinda short, like some people noticed but It relies on you to do multiple playthrough since you possibly can't visit all the stuff there is in one go.
It's only short if you blaze through it. And even so i wouldn't call ot short. It's 12 stages and you aren't gonna steam roll every boss. You need to figure out their gimmick.
I have been exploring and i've died to time over a few times cause of it. The levels are huge and full of secrets.
Also, if you do the bonus stages and special stages it won't go by that fast.
I am pretty much half way and have been playing for... 4 hours. The only thing that irks me a bit are the special stages, Sonic is so slippery. >.<
If you don't rush this is an 8 hour game and tbh would've been fine if sold for 60€/$. For 20€/$ absolute steal. This is the equivalent of sonic 3 + sonic & knuckles. Back in the day, it would've set you back 120+ €/$. Incredible value proposition.
The game is also definitly harder than S3&K. I've unlocked some skills wich i won't say anything about cause of sort of spoilers but i still don't know how to activate them. Bit odd. Maybe in further playthroughs they get unlocked.
Definitly a very good game. Those low reviews are criminal. Anyone that rates this a 6 or a 7 doesn't deserve to be credited as a reviewer. Theres only one flaw in the whole game imo wich is the slipperyness of the special stages.
