Difficult, yet addicting platformer.
This is a pretty challenging game, especially if you want to get all the coins.
A thing I found weird were that I can't get all 8 coins as the "Ninja" (Only 7 exist in the levels), but I can get 10 coins when I go through the levels with Meat Boy, is this intended, or a bug? Because it's pretty misleading if you can't get all 8 coins on the first run.
Also, the "jump" button shouldn't be the skip button at the ending screen. It's not really a big thing to worry about, but I accidently skipped it my first time beating it and It just annoyed me a little bit because I felt like I missed something.
But overall, it's really good, I get this "I Wanna Be The Guy" vibe from it, as in the clever traps and the way it plays on your patience. Except, it's not brutally unfair.
The only thing I feel missing is a story and maybe it could be longer.
P.S. To the people who think they double jump when they press "jump" once. It's because if you run off a ledge and press jump, you'll automatically do a double jump, but waste the possible first jump, so you have to be careful.
