Oooooooooooh noooooooooooo! You really wrote "(some of which are good)"?
... For your concern, didn't you ask yourself what can happen if a player read that only SOME of the levels are GOOD? You see what I mean? He will automatically think that 95% of the levels are bad...
What do you want the player to expect from your game? Don't miss that each time you upload a game and have to write a convincing text.
