I won't lie, the lack of a level restart button is a bit frustrating, but the mechanics themselves intrigued me. I tried to progress all the way to level 4, but the path that took me up couldn't kill me because I had no jumps or dashes, and spikes don't kill me. And again, completing the entire game seemed too long. But in any case, the art is beautiful, the mechanics are well-designed, and future tweaks to the interface and some audio effects could make the game extremely enjoyable. Good luck!
