The breating mechanic's really interesting, I think to improve it something should feel clearer about whether you succeeded or failed, and when you should start doing it again, such as with an indicator. Other than that I really liked the arrangement of the objects and the mechanic of dodging is simple but really fun combined with the breathing. I also wonder if the breathing indicator should be tweaked to be a little bit less intrusive on the screen as it may interfere with dodging objects. Overall, I think you did a nice job on this unique game.
