Its really good, i think there is lots of potential in it but i think some tweaks here and there could improve it a lot
-increase font height by one pixel (most minor detail not really necesary but i really don't see it breaking anything there is plenty of space left on the screen)
-increase overworld move speed (i dunno if it is that slow due to generation times if it isn't i think the character moving faster would make traveling more pleasant)
-add some way for the player to be able to tell which room borders lead to another room, while on a cave i was constantly getting to borders and they would lead nowhere which was kinda frustrating since the character moves quite slow
-the game crashed while i was raiding a orc camp
