Yoohoo~ Chewed through this in about an hour, and I'm quite impressed! For a game this new and early in (potential) development, it was both enjoyable AND I only had two minor gripes, being that A) there's no way to stop the auto-spawning fractals once you've bought them, and B) the stars ALWAYS spit out random fractals among the ones you own (the auto spawner also does this, but that can be counteracted by implementing the prior note)
I'm hopeful this'll be worked on further, and DOUBLY hopeful it'll get ported to Mac with the Steam release (if not, oh well, I can always play on Itch in browser)
(For the record, when I say chewed through, I just mean "played until I felt done" which in this case includes completing ALL achievements, even the ones not implemennted)
