I just got off the train and started the Rainbow Butterfly Woods. I haven't had too much trouble up to this point, but the enemies are beating the crap out of me in this level. I'm on the 3rd floor and can't seem to get anywhere without getting killed. I have upgraded my weapons a couple of times, but haven't been able to do anything with my defensive areas or increase my HPs. Any advice? I really like the game, but it's so frustrating that I haven't played it in a while. Thanks in advance.
