Hey no problem Mete!! You could potentially gently sprinkle just a few obstacles in earlier levels, I think like level 11 is a good starting place. The good thing about your game is that since it's so simple compared to some giant AAA project is that this kind of issue potentially may not be as much of a mess as it could be (I dunno what engine you use so maybe's it's an insane process I dunno LOL) Keep up the good work, I super look forward to seeing what's next!
