Definitely one of the better programming loop platformers out of the lot. I played through the whole thing and I was quite impressed by the novelty of the design. It felt pretty good and it was snappy, always leaving you intrigued rather than frustrated. Even the slightly loose puzzle progression - which can be a problem in some jam games - work really well.
Small critiques:
-The sound could have used some better balancing.
-A few of the levels felt slightly out of order in the progression.
-A way to erase all current nodes would have been welcome.
Really great work - I had fun all the way through.
