A little tip is to use your money more wisely as you don't get nearly as much as you do in Path of Radiance. I never had serious issues with it, but I racked up so much money in Path of Radiance and was able to buy whatever I needed whenever I needed. I can't remember exact parts of the game, but I definitely had to watch my spending (maybe not getting the killer weapons all of the time haha)
Oh, and also check the shop often because Aimee does sell some pretty sweet stuff, like skills, weapons, and stat boosters if you're into that!
