My main gripe about this place, is that it seems rather pointless risk/reward doesn't seem worth it. On top of that, the enemies really feel as if they're unchanged from LotGD. Right now I encountered a0 Disembodied Spectre which lunges at you with ghostly powers. Doesn't really sound very Naruto/Ninja-y.
The enemies should be easy fixes. They could be something like, 'Failed Kaguya Experiment w/ Inside-Out Body' or 'Manda Clone w/ Deadly Venom' or 'Ninja Prisoner w/ Curse Seal' or some other suggestions.
And as for risk/reward, we all know there's plenty of instant deaths that can occur in the hideout but the enemies you encounter there are also extremely difficult. After completing the dungeon, this is my reward.
You finished the maze in 159 turns.
You find a treasure of 0 gold and 0 gems.
I know you're going to say 'Oh, you didn't make it out fast enough', but even when I had, it wasn't really that great of a reward. Would it be possible to make it a rare random encounter within the hideout to fight Orochimaru himself (doing so would be able to net you an Oro kill, maybe?) but he would be extremely buffed up (kind of like the chipmunk boss) so that it would be difficult to actually kill him and 'skipping' that Oro kill would actually be hard to achieve. Either that, or increase the amount of stuff that you can get from completing the dungeon by adding items to the things you can get by completing it.
