yeah that jump thing was a bug and i couldnt fix because i submitted the game and after submitting i knew there was a jump bug
and for the menu you are right about that i shouldve added something for it
and the reason why first level is hard is that i had my full energy doing it so the game came out : easy = hard , medium = medium , hard = easy
the rest you are right in them too
thank for the review and this is my second game by the way so i had the lack of experience
