Nice idea, creative design and a catchy tune. A very good start. Needs a bit more polish here and there. Some controls' explanation, different music for the different levels /dreams/ and maybe it will be better if you lower the hardness a bit. I managed level 3, but level 4 seems impossible. You'd better keep your players "attached" for longer. Progressive difficulty is the best one. Of course, the last level deserves to be called "the ultra nightmare one" Keep up the good work. Looking forward for version 1.01.
