I went looking for a naruto MMORPG the other day because the official one sucks and to my surprise I found the exact thing I was looking for - the SLO.
As a natural sceptic I was expecting to find basically a general MMORPG such as silkroad with a naruto skin and to be honest I'd be happy with that already but you guys went several steps further and actually made something much deeper and definitely more interesting. Kudos for that!

Speaking only about the downloadable version, the first thing that caught my eye were the graphs, really great stuff much better than what I was expecting for a reasonably small indy game and the performance is not bad either, I have a 4yo AMD Radeon 7670M and it ran smoothly at 30fps if I took off motion blur and dialled down on the graphs a bit, with the fastest graphs it could run at 60fps even with rain and a 3x3 pvp in the stadium. Although I'm also aware that there's still not many structures in the game.
Took me a while to figure out how to run and I'm still not sure if it's too complicated or I'm just not used to it.
The jutsu and hand signs are pretty creative, I was thinking there were set jutsu that you just select and click to use but this way is so much more realistic (ironic I know) and it'll provide much more interesting battles, I just which there was an easier way of making the handsigns, it requires me to take one hand off either the mouse or the asdw which kinda leaves me vulnerable for a while, I'd suggest something but I'm honestly not sure how to fix it either.
The jutsu aesthetics are also pretty cool apart from the wind bullet which kinda looks like a spit, the white should be more faint imo. Speaking of which the character looks kinda dumb if we get him to run while making signs.
After a while I was having a great time teaching a new player al these little things and getting accustomed to the controls when a brazilian dude with more experience logged in. He didn't even wait before hitting us and completely neglected our warning that we were still getting accustomed to the controls. Afterwards he even kept killing the other dude who said he was going afk for a while (takes lots of skill to kill an afk player) and me while I was typing out of the arena, if there was a way of reporting him for unfriendly conduct or something on that line that'd be great, completely killed my mood to keep playing the game for that day.

As for the planned parts, I've been taking a peek at some ideas of the devs and I'll just post my thoughts on them.
Love the idea of making this a true world with real kages, I'm not sure if you're planning on expanding this even further but it could be interesting to have more jobs such as military police force, anbu, teachers, bounty hunters, etc and a major event for promotions from genins to chunins and jounins, have a set of rules written by the kage if you fail to follow those rules you could become a rogue ninja, etc etc etc
It'd also be cool (I think) if a battle didn't kill us but put us knocked out, then if the other player kept attacking then he'd kill us indeed and we wouldn't be able to play with that character anymore.
The idea of making chakra natures is also pretty neat!
Oh and last but definitely not least, we need character customization! Although I reckon with this many details it's probably already planned :D
