OK. To get an easy gate entry, what you have to do is: Go to the first 2 levels. Go into Toon Town, I think, [I don't remember it's name], and get all of the levels completed.
Then go to Scream and do the blood container thing. Then, go over to the new level,(you should have four remotes) defeat it, it's easy, and the gate should open for you.
Go into the chinese and Techno levels, and for the Chinese, it is pretty easy, do all of them, and for the techno do two. You should now have enought to unlock another level or gate. If not, go back to scream.
