1. You need to visit the village chiefs house for permission to leave. You get a scene there.
2. After the scene chief tells you to find some guy in mountains so you can learn some skills. You need to bring him 3 garlics, which drop from mobs or can be picked from ground.
3. To get to the guy you need to go left once you get to that crossroad(place south of village). You need to jump over the that wooden barrier by pressing S. Once you get inside the forest you need to jump until you get to that guys house.
4. You can trade garlic for new skills when you talk to him.
5. You need to go top right in crossroad until you arrive at that little place with all the bad guys. Loot everything from houses and then go north. You will see the entrance to mine there, so jump over the barrier and go inside. Kill everything there and you'll get a key and one of the 5 bastards that killed your father when you were little is there. Inside some vault you're also find clogs from that guy in mountains. Deliver it to him and he'll teach you how to walk underwater.
6. From crossroads if you go bottom right, you'll get to town. If you enter the biggest house on the left side there's a wallpaper. If you click on it, you'll find a hidden entrance and another of the guys you need to kill is probably there. He probably gives you a key for the next boss. I've not yet killed him but I'm guessing he there.
7. From the town you're right now if you go south, you'll reach the lake. If you learned how to walk underwater by returning clogs to the mountain guy, you can walk to that little "island" in the middle and loot the key from the chest". Go bottom right from there and you'll reach a temple. If you manage to kill the bad guys there, you can loot demon sword from there. Bring it to the mountain guy and he'll give it to you. Equip it.
I'm here after few hours. There's tons of things still to discover

Gonna take a break now and continue later.
Things Good To Know:
- You can loot every day from the houses
- It might be good to go to main town at start(south from crossroad) and buy equipment from the shop. To get to town, you need to either bribe the guard there, or jump over the south wall and bypass them. Be careful, there are two mobs there which can be hard at start.
- Collect garlic since you can only buy skills with them.
- Learn Shadow Clone Jutsu asap because it makes everything a lot easier.
- Once lust reaches 100, you get option on main menu to lower it. (Masturbate)
- There's a hidden place inside village chiefs house where you can loot 50 dirks and healing items. It's located in the top left corner of the house where that paper is.
- You items can be destroyed. You need to repair them after they've been damaged. There's a guy in the main town that does it, and some old lady in starting village.
- You can obtain ninja cat, ninja dog and ninja hawk once you get the Scroll of Animal Training. Hawk is located in town if you go bottom right from Crossroad. Go to the southeast part of the town and use water camouflage and walk until you reach the place where hawk is. Cat is located in starting village. Dog is in the main town, south of crossroad.
- You can change pets names from the main menu. Once you obtain a pet, you'll get another option on main menu.
