I'm so sorry this doesn't get more views; pretty amazing! Deserves more recognition.
It runs smoothly and nicely on my laptop (xps 15 - 960M).
It's amazing and overwhelming to go through those shapes and caves. It kinda gave me the same feeling as NMS (which is a compliment, I think NMS was really cool - minus the survival stuff). I wish there were more varied shapes, because it does get boring after a while.
If I am the target audience, and if you'd like to expand on the concept, I wouldn't add gameplay at all, but focus on having more shapes, colors, and maybe being able to shrink/grow. Maybe add moving parts, or maybe mix different types of fractales (such as chunky ones that look like cities). The more time/money budget I'd get, the more I'd add weird things, procedurally generated insects and life, trees. But I can't think of good gameplay to add to this (maybe I just haven't thought of this enough).
Very interesting game, thanks a lot for putting this out.
