many mistakes!
look m8! i love games like this but the collision detecting doesnt work so good and did u even test if the score worked? wen u get coins te score dusnt go up it really seems like it took u half an hour to make this u should test it first next time and keep this as a reference because im sure newgrounds doesnt want to see your unfinished or should i say not working game!
please fix these and add levels and stuff and maybe people will like it
