i know what it's like when you put down a game and later you completely forget what you were doing. that happened to me with pokemon firered after not playing for months.
Jae- oh, so you're in the forbidden woods? when i first got there i was stuck for ages, but then i came back to it months later and i'm like "oh, this is easy" and got through it. that was one of the ones where it can be really easy or really confusing depending on how you approach it.
Kenza- noooo that's horrible! if you have a sibling, i suggest pinning it on them and convincing your parents they lost it and now have to buy you a new one. xD if you don't, oh well, i have a new idea for future reference.
I tried playing Spirit Tracks last night, but i cannot figure out what to do. i will check a walkthrough before trying to play again, because that's what i do, the moment i get stuck i go straight to a walkthrough. xD i'm just reeealy impatient, lol
