Keep at it; your next one will be better! I imagine the maze was time consuming to create and was possibly the crux of your dilemma. It was a neat thing to see: how the player glimpses a little maze underfoot, to then have to traverse the big maze. I suggest instead of taking the time designing a complex level layout, focus on what you'll have the player do and then design a few key pieces that serve that. A simpler maze would save you time/effort and still accomplish your goals. Good effort, keep on learning!
