Considering the tight development window, a triumph of lateral thinking. Would love to see a roguelike version with randomly generated knot demands, conditional abilities like one forgiven mistake per knot, a brief period of reversal, or a slimming of the string for greater control. And in that paradigm a personal best tracker so I can see how many waves I survived each time. Also some simple lofi elevator music/8 bit ambient might be nice to make it feel more open. Lastly some razzle dazzle applied to each win and loss could help motivate play. Even simple "nice job/you win!" type text triggers reward centers in a big way, but sudden saturation increases, animation, texture shifts, etc. are a satisfying confirmation of success. This could transition to a legitimate steam listing with relatively little additional complexity above its current state honestly.
