I really liked this game! Sure it is not easy, but I feel like a few people are criticizing it unnecessarily harsh. It took me about 30-40 minutes to finish it, and sure there are some difficulty things that could be improved, or maybe different difficulty settings like for example visualizing the cirlce you have to stay it (and making "retry" selectable from the moment you mess up so you don't have to wait) - but other than that it is really polished and I feel like the difficulty made it more fun in the end :)
