the only tweaks that are being made (so far) is fixing typos and glitches.
yes, the game is hard. but its "old school" hard, not cheap, broken gameplay hard. i think it has this reputation because people raised on modern games are so used to the non-stop handholding. this game leaves you alone and requires that you use the block button, use caution and play smart. there are no checkpoints, if you get killed its back to the beginning of the "level". early on, you are required to "grind" for souls (currency) so you can upgrade your items and stats.
i think anybody who played truly hardcore games like wizardy when they were growing up, would feel right at home with this game. or if youve played the ds game dark spire, this is the more action oriented 3d equivalent.
