Yeah! Cloning staff is super powerful... imagine having two of them, you will be able to duplicate items like potions or scrolls. infinitelly
I have plans for a (future) big update; adding more dungeon layouts like caves and optional (hardcore) areas like a maze (with a minotaur and a treasure). But I need a lot of time to implement that. Red messages will be super usefull to complete the maze fast.
I will think about your trap idea btw :)
Next update is to fix some security bugs. Then I will focus on the future big update with more content.
