hi all - i just bought this game and am enjoying it thoroughly. there's just so much stuff to do. anyway, i noticed that sometimes, i get a symbol in the upper left-hand corner. i'm not sure what they are. when i click them nothing seems to happen. they'll even keep "stacking" from left to right across the screen. i think one time when i was trying to open a barrel, everytime i clicked the barrel i got another icon. can anyone clarify? also, if you have any general comments, suggestions or tips, i'd love to hear them. i don't want to play the game in any sort of cheat mode (yet) and i'm not using any strategy guides (yet)...for some strange reason i'm actually trying to play this game "legit"!
