Ok, so I have lots of mixed opinions about this.
I feel like the idea for the game is a very common idea, and something that will be overused too much, but that being said, yes it is a common idea a platformer with no keyboard, its the way it was executed, using your mouse to sort of lift it up and throw it, it both makes for a great and challening as hell game, the music and art fantastic, there are a couple of bugs when using webGL but its still great and its not your fault.
I give it 4 out of 5 stars!
Really nice game, good job! :)
