You probably know about my review of Sonic Labyrinth, but I didn't explain why I hated it enough.? So now, I'm about to do this game justice.  No messing around, time to tear apart this atrocity bit by bit.  It's never explained in-game, but Eggman/Robotnik or whatever the heck you wanna call him decided to remove Sonic's speed.  So he decides to switch Sonic's shoes with these heavy sneakers, and sonic can't remove the sneakers without the Chaos emeralds.

Sonic gets trapped in a labyrinth by Robotnik (Not sure how he managed to do that) which is under construction.  In doing so, he breaks Good Villain Recommendation Number 60: Make sure you finish a prison before deciding to capture the good guy and imprison him or her in it.  Anyway, let's move on to the actual gameplay.  Sonic moves at a pace that would disappoint a Roggenrola, and can't jump, but at least it's explained why sonic can't go fast without a powerup!  So the only way to kill enemies is to spindash, and you can turn the spindash around to a degree, but if you go too fast, you'll run into a wall, and bounce off of it.  You have to find three keys to exit the level, but you have to find the exit as well.  But if you get hit, you lose both every key you have, and some time.

Okay, I can't take it anymore.  Bottom line, Sonic labyrinth gets a 2.4 out of ten! Okay, I'm done here.  No plagiarism is intentional whatsoever, if there is any.
