First download Cheat Engine, from  this link. There will be text that says 'link: Cheat Engine 5.6.1' somewhere on the page. It's really easy to find. Click Run on the window that should pop up. Download, install, change some things in the setup, yada yada yada, but save CE somewhere so that you can easily find it later. Open up Cheat Engine, and N. In N, go to some random level. It doesn't matter whether it's a user-created level or not. Just any level. In CE, click that computer icon on the top-left corner. A window with a list containing several processes and winows that are currently open/running should pop up. Scroll down, and find a process called  (address)-n_v14. Select that and press OK. There's a tick called  Enable Speedhack somewhere in the mid-right of CE. Tick that, then select whichever speed you want everything to be. (don't choose 0, or 100+.) Then when you've done that, hit  Apply. Congratulations, it's been hacked.

Hope it worked.

NOTE: Speedhack hacks EVERYTHING. That includes enemies. Don't think that it only hacks your ninja.  

Post, someone -_-

interesting. I'm not really interested in hacking N (at least not right now in this very moment), but maybe this should be a blog post.

It's just for personal entertainment, not for personal achievement, remember.

you can also speedhack other games and the process is vurtually identical

I tried HatPC, but that didn't work. So no, not necessarily.
