If you find the stairs and get the "Go down to the next floor ?" message and chose "No", the stairs then completely disappear from your map. You can still see and use them, but not see them on the map.
This game would be great without the bugs : it's impossible to upgrade health, it asks me for my name but only accepts the letters A, K and M, sometimes it won't let me talk to people and I have to get out of the town and come back until it magically starts working again, etc. (using Chrome on a PC)
Ultimate battle strategy in this world :
Sew a flag that looks exactly like the ennemi's one.
Send someone to burn their flag.
Show your fake ennemi flag to make it look like you brought back theirs.
Unlimited mode should have some kind of speed-up button : just have the game calculate the result and time it takes, and you can continue playing. Else, this can easily become : wait 2 hours, buy upgrades, press space, wait 2 hours...
