Im guessing when the spanner is filled and all 3 gears are coloured the game is ready for release?
Don't worry about the other icons, the ship one is important, because if it's full it means the game is shipped. <drumfill>After the wrench is done do we need to pass the 3 magnifying glass, the android character etc..or after the wrench is done it means it's good to go..? ( i don't understand one thing with this progress bar even if i like it)
