I'm actually hoping games like this don't get thru anymore.
The synopsis would be "Nothing new or interesting."
You mentioned a twist, but I never got to one, since I've played 400 platformers which were totally the same game as your game is, thus giving me no reason to let this clone thru.
There was a problem with the controls. When jumping, the controls are really wobly, making spots like "Level 4" pretty hard to get thru.
I apologize for not really reviewing the aspects of your game that much in this post. It is simply due to the immense overflow of games that are in no way different than this.
If you love what you do, you'll have to think outside the box. Think of something new!
Keep it up.
