I bought it for a long time. Just play few chapters at beginning. Just feel it as a another mario game but VR mode. So left it for almost a year. This week , just play it again. After more and more chapter were completed. I start to aware I was wrong. I overlooked its excellence. The whole design including graphics, traps' design, difficulties, and every details are excellent. I start to realise really lot of effort to develop this game. It also includes plenty of chapters. I am using 10 hrs just achieve 54% completion. The whole experience is really really funny.
