The controls are horrible, and we have to wait once in a hole to die...
The sound is not here, so we lost a lot.
I would recommend you looking out for jump buffers and input buffers in general, as for better controls and a good responsiveness.
The originality of the game is here, just lacking the good platformers movements !
I would recommend spending more time play testing your game before coding more.
Thanks for the game, and I hope you'll take the time to try mine too :)
