Thank you for your comment!
It's true that a lot of unique level mechanics could have been developed further, I'd love to release more levels eventually!
Your trail suggestion is quite good as well, and I can imagine it helping with the jumping over yourself levels as well. This was something we actually briefly discussed internally, but I was quite sure how to display it elegantly. In the end, I ended up using lines only for when selecting a past clone. If I get to work on this further, something like that is sure to be at the top of the to-do list!
