The music and visuals together are mesmerising and it's fun to watch it grows. Frankly, I didn't understand the mechanic of growing paths or how to control them (sometimes I had the feeling it did anything but what was the best for it).
For the future, it would be handy to be able to speed it up or probably make it into some AFK grinding game (it would certainly hook me). Overall it's a very nice entry and I quite like it.
