i see, and about the cave i have been stuck out not inside but outside of the cave, in the black wall,i don't know about the unpacked thing,maybe can you explain better about it?
When you downloaded the game, you need to unpack the archive (right click and extract here) to have the game folder unpacked/extracted. When you do the save in-game, minimize the game and check the game folder for the save file, it should be in ".../www/save/fileX.rpgsave", where "X" is 1,2,3,etc depending on the slot you've saved.
I'll try to recreate the cave bug and hopefully this can be fixed, too.
