You thing you failed to realise, torcherboy10, is that they make you pay for most of the game's content. I wouldn't be surprised if they added a brand new area, above the Palace and requires you to pay to unlock it.
I survived explosions, mutilation, setting myself on fire, getting punched by God, bit by snakes, hit by an anvil and even atomic-body slammed.
Papercuts, not even once.
Okay, so a quick little answer for 4. I found that some of the answers are a bit convoluted, so I can dumb it down a bit.
Each number has a unique position, take note of it's position. If it's a 2 in the upper right, enter a 2 in the upper right position on every keypad. Do the same for the rest, a 6 for the lower left for example or an 8 in the lower right.
I felt incredibly stupid when I figured it out.
Ok, so one big issue I have with the game aside from the broken record is the upgrades.
The need to rely on other players to upgrade your Improvements completely can be completely ruined because of lack of cooperation. It may depend on the guild, but it shouldn't have to leave my guild to have my Improvements upgraded. I've sat around for a week waiting for upgrades to come, with very little progress in the Carpenter side of things.
The ability to upgrade your own Improvements, with or without diminishing returns, would be very welcomed.
NPC: Bleh, I guess I could trash it.
Or, you know, you could sell it for a lower price aside from 150% of what it's worth. That could work, greedy bastards.
