Okay 10#.
Art: 7/10 - Pretty cute the player you've made but you set it to loop forever the animation, plus you didn't even give the platforms some arts, but you mentioned that you rushed this game.
Music: Sadly there was no music so I can't rate this.
Gameplay: 8/10 - Simple single level platformer game, with a little trick. I can't seem to find the door.
Overall rating: 7/10 - Oh come closer, participant, don't feel bad about you rushing, there are few people that did worse then this.
Note: I hope you learned some new things :)
