Needs work
Overall it's 'meh'. There's nothing new or exciting about this game. Graphics are nice but that's about it.
Enimies are not easy to avoid with or without using the Stealth ability and I find myself running away more than fighting them. Staring with ninja stars would help immensely.
Boxes are a HUGE problem. If you destroy one that you need to reach a higher platform its gone for good? Or if you move one to close to the edge of a higher platform and fall down, guess who can't reach that higher platform again, you! Wow that's lame.
Also, waiting for the old guy to finish talking sucks. Issue a hotkey to speed up hit chatting.
