Well it's glitchy...
But that's not why the low score. Actaully I found this game really entertaining. Just so you know I've wnet through the whole game and played all the levels. Not a bad game if I do say so myself.
I found the start screen very creative. I love the way the words were set up and it's just a nice neat little screen. It doesn't have much negative spaces and it is mostly filled with what the game is mostly about.
The instructions are simple and easy to understand. Only one page of knowledge needed to conquer this game.
It's very glitchy, but fun as well. I don't understand why these people are saying it's hard. The only hard part is falling through the ground. That's the only handycap in this game.
But it does need improvement. More levels, enemies, goals, it also needs a couple of lives, or checkpoints. I couldn't stand dying the first time I fell and having to restart all the way at the beginning was a pain. But nonthe less it added to the difficutly.
Good job, and I hope one day to see another platforming game from you.
