Heya!

I can't say much about this, but one thing is for sure:
You have to Fear the Death.

You can't just simply go and die because "Hey let's zombie that great buffalo lol" or "Ok, time to lolteleport" or anything else. You get KO'd. You lost and you have to suffer for that. Like Yoshida said it's needed to create "a sense of nervousness regarding battles", which is needed for the purpose to have fun. I know that "Dying" and "Have fun" can't find a context together, but it adds more Adventuring, which is Fun.

I'm in the side that says this game needs more harsh death penalties, so let it be or enhance it!

See ya!
