Clicking 'Sound off' really needs to turn ALL the sound off, not just the digging noises. Having the background 'chatter' still there kinda defeats the point of having a mute option.
This applies to more than just this game, but in games like this, you never want to NOT be shooting, so having to hold down the button is just unneeded strain on your finger.
Kills hundreds to save his own skin, even kills creatures that offer him riches only to loot said riches from their battered corpses... I'm starting to get a sneaking suspicion just why they don't want him on the boat.
Easy, quick and safe(ish) way to get money:
Go down south and buy as much iron as you can carry in Toccuna. Take the iron to the town just to the west, Firetail, and sell it all there. Then buy up as much timber as you can afford and return to Toccuna to sell it. Continue going back and forth between the two cities until you have all the upgrades and gold you want.
After achieving a gold star in the Antarctica level and getting the camera, you can 'reset' the frame-rate by clicking on the camera icon and then exiting back to the level(no need to save a screen-shot).
