I can see the effort you've put into making '4096 odyssey' challenging, which is always appreciated by fans of tough games. However, I agree with some of the comments here about the level design being a bit confusing at times, especially with hidden areas and the difficulty spike at the -2 part. I think a little more guidance or clues within the game could help players better understand what they need to do, without making it too easy. Keep up the good work!
