This game is terrible. The graphics are messy, the movement is stilted, and the controls are confused.

I'm sorry, but for me, this game was unplayable. First all, you have the options of 'Start' and 'Continue' in the main menu screen. It should be one or the other...or at least open up the continue after you have a first play-through.
Secondly, the gameplay is not a good design either. The having to constantly look at the bottom of the screen at the skeleton gets distracting when you need to concentrate on the top of the screen. The skeleton guessing game isn't hard at all... you just reversed syllables and that's it.
The movement would be fine with the arrow controls only. Right/ Left to move is fine. Up to jump is fine. Up, Up would be much better as a double-jump, rather than the jump/ attack. By the way, the jump/attack combo does not work in this case. There is too much lag in between input in order to have precision jumping, which is needed.

That being said, I couldn't get past the first wall. Now, I know that I'm not an expert gamer, but when I can't get past the first wall trying wall jumping, double jumping, and the jump/ attack combo (which s what I was 'supposed' to do, but could never get to work), then we have a problem.

Overall, a platforming game and a skeletal learning game would be fine separately. However, this game is like trying to combine peanut butter and a mitre saw; they do fine on their own, but there is no reason whatsoever to try and bring them together.
