Bought Deep Labyrinth the day it came out. Loved it; spent close to 20 hours playing both scnearios. While it never gets hard, per se, it will get a bit more difficult the further you play. And Chapter 2 is harder than Chapter 1 (I've actually died in Ch. 2).
Remember you're only 2 hours in. The mazes get way more complex as you play (the very last area of Chapter 1 actually took a long time to get through totally, several hours if I recall correctly).
But yeah, it's an easy game, on the whole.
Yeah, I like Deep Labyrinth. While I haven't beat it yet, the game is fun. It's also fun to just laugh at the retarded girl you talk to in the second story. She's kinda weird...
Is she ACTUALLY a tard? It'd be hilarious to have one or two of those in a video game.
