Hope you get new headphones. Perhaps do a Kickstarter?
A good experience. So minimal and cute it still feels like a maze game. With the annoyance being subtle so it'll sink in later. Doesn't seem to handle the case where you run the shortest path and survive (4 of 4 blocks). Probably fixable by adding your mood into the result (and probably removing the block counter or clarifying it was a trade).
If You're planning to add sound: I know I'm the type who would be more responsive to audio queues when they are "neutral" through silence or silence-like ambiences (h2 bombs in https://www.youtube.com/watch?v=Mh5LY4Mz15o or the strike in http://www.killbox.info/ / https://www.youtube.com/watch?v=6_KfGCUDUSc ) rather than dramatic (most drama films). But hey, depends on your target audience.
