Boring and Badly Designed
The opening movie/comic thing made the game look a lot better and more polished than it actually is.
Controls are pretty shocking especially the hit detection and jumping, Art style is great but pretty much wasted of the poor design.
Honestly got too bored and frustrated to continue playing within the first 5 minutes.
Also, the loading scheme is terrible, i just want to load the whole level or chapter before i get to play it, i don't want to sit through 15 seconds of loading every time a traverse a screen. I'd rather have one long wait than 20 short ones, it breaks up the momentum of the game and makes the player lose interest very quickly. There is no place for this loading concept as if you have a good internet connection then loading isn't an issue and you can load a 20mb file easily. If you have a crappy internet connection then you're accustomed to waiting and will probably start loading a game and then go and make some tea or something, they are willing to wait. Nobody wants a game that needs to load every 15 seconds, it doesn't help anyone, ever.
Focus on making the game actually worth loading before trying to implement a complex loading system.
