I think it would be better to have the subfolder inside the zip file because although sometimes it is a bit annoying to go like hello_adventure/hello_adventure/adventure.bat, it is much worse to make a big mess in the current folder that you then have to piece together and clean up.
how did you get the mouse to work? That is so cool. I liked the apothacary and lvl2 dungeon art that was nice. I guess you are using the LowLevelKeyboardHandler to get input while not focussed? That is annoying why do you do that is it so that you can accept input while text is highlighted or something?
It is surprisingly graphical for a CLI game. I died to a bat on level 3. Nice game, but it did seem to lag or freeze up or just not receive input sometimes, weird.
