Cool game, might be a nice game for mobile as well ;)
I don't really see the topic angle of it. Anyhow I like how smooth the movement is.
I think it would be nicer that once you collect a node, it doesn't respawn behind you rather the rope appears and then you drag it along - would look much more natural -
Also I found out in the end that you can use Up-Down arrows.
Overall, nice submission
