To be honest, I have to agree with everything EpicMooCow said.
The music quickly got annoying, the pixel art is nothing new, original, and inspiring, and the storyline leaves MUCH to be desired.
However, I'm the kind of gamer who's actually willing to overlook these kind of things for good gameplay. After all, I can always just mute the game's music and put on my own, and the storyline is often only secondary to the gameplay.
But, you see, that's the problem. The gameplay is absolutely terrible. I played through about 30~ levels before getting utterly bored (and frustrated) with this game. Why do I say the gameplay is horrible?
1) This game is labelled entirely incorrectly. Nothing about this game is action, and calling it a platformer is a bit of a stretch, my friend. If anything, this game is a puzzle game. After all, it's not like you're free to move (a key element of every action game). You have a limited number of jumps, and must think and plan your moves to be able to collect all the mana bits before running out of jumps (sounds like a puzzle to me...).
2) There is a fine line between making a game difficult, and making a game frustrating. Difficulty occurs when the goal you're after is challenging. Frustration occurs when the goal is not necessarily challenging in and of itself, but is made so by bad gameplay mechanics. In the game, you constantly had us trying to hop onto platforms and into chutes that were exactly one block wide. Considering how sensitive sideways movement was, and the fact that you CONTINUED TO SLIDE ON THE GROUND AFTER LANDING, this was made into an impossible task. I often had to retry the same level upwards of 30 times just because I kept sliding off the one block wide platforms. Remember Skudge, not everybody has pinpoint accuracy, and those who don't are not going to spend hours trying to learn and perfect the game. They, like me, will just give up on the game and go do something better with their life.
3) It was boring. After about the 5th level the game quickly got repetitive. Throw in the frustration that comes with it, and well, your game's gonna bomb.
I'd highly recommend working on, if nothing else, the game mechanics, so that this game isn't quite so goddamn difficult.
