Being able to upload maps for other people to play is certainly an exciting feature. I can see that your universe is already rapidly expanding. I have been trying to find my way around all the strange names of places and tyrants. Perhaps there could be a way to see the author's description? Might be fun to be able to invade more than one map with the same hero. Thanks, I know a lot of people will enjoy it.
I mean invade more than one map one after another, without restarting the character.
I really like this idea! Perhaps there could be some kind of system that rates how difficult a keeper's dungeon would be to take-on and so when starting, you are put on an easier map, and then as you become more powerful and conquer your first keeper you could choose to venture to a realm which is potentially more dangerous (e.g. larger rooms housing more creatures or even saved creatures being much higher level with more unique weapons and so on). The system could potentially take into consideration the extent to which the keeper of each map loots their enemies, and thus the scarcity or abundance of support items/more powerful weapons and armour would also factor into the difficulty rating of each map.
