Can it get repetitive? Yes. But if you loved the first game, don't let the mediocre reviews scare you away just yet.
The good:
Entertainment value- It's fun. Maybe not as innovative and fresh as some would like, but I really had fun playing. I liked taking down enemies and exploring the environments.
The level design- The levels were diverse enough in appearance and some chapters managed to be beautiful and creepy at the same time. The platforming aspect of the game felt natural, and they did add some challenges (like invisible platforms) to keep you on your feet.
The UI- I thought navigating the interface was simple and easy to manage once I got the hang of it. Weapons are easy to switch between.
The puzzles/strategic aspect- The game incorporates puzzles in both obvious and subtle ways. Sometimes you are asked to move around blocks to form a picture or move across as chess board, and other times you need to figure out exactly which attacks should be used to best bring down a tough enemy. The shrink ability-which allows Alice to...well, shrink to fit in certain passageways- makes the chapters a tad less linear.
The bad:
The story- Okay, it wasn't ALL bad. This isn't really the type of game that strains characterization and plot lines in the first place, but I got a little tired of the story. Alice is trying to discover the mystery surrounding the fire that killed her family, but the way that the story goes about it seems disconnected and random.
The enemies- There's good AND bad to be said about the enemies in Alice: MR. I thought the enemy designs were really cool, especially the dolls. Nothing creeps me out more than seeing a giant baby chasing me around thirsting for my blood. The problem I have with the enemies is their repetitiveness. There just weren't enough different kinds of enemies. It seemed like I was constantly fighting the same guys- though some chapters do offer more variety than others- for most of the game.
Repetitive game play- Not much changes from one chapter to the next. You hack, slash, and shoot your way through the levels, fighting the occasional ambush of enemies and bosses, shrinking here and there to get through passages and figuring out a handful of puzzles along the way. I was ok with this- I had fun hacking my way through the enemies and navigating the levels.
The messages in a bottle/the snouts- So the developers must have thought that their game needed more of something. So what did they do? They added crap to collect. There are bottles containing messages throughout the levels- as well as memories that Alice can collect. The fragmented memories at least give you a brief bit of dialogue from Alice's past. The bottles, however, don't seem to benefit you at all. They're just there to collect. Just because. I found this annoying, especially since my inner gamer screamed to collect as many as I could, only to find out that they were useless.
I also didn't care much for the snouts. In the game, there are pig snout that you can shoot to either reveal pathways or grant you prizes (mostly teeth, which are the currency in the game, and health). The snouts are sometimes visible, and other times invisible. The way you're supposed to find them is by listening to their oinks. This gets old. Fast. Especially when you spend 5 minutes listening to oinks without finding a damn thing.
To sum it up...
If you liked the first game, give this one a shot. Go in with modest expectations and I don't think you'll be disappointed. It's not the greatest game I've ever played, but I honestly had plenty of fun playing it. It's worth your time as long as you accept it for what it is- a fun, if somewhat repetitive, action adventure platformer with the nonsensical twist that we expect from Alice in Wonderland.
