Well that was incredibly infuriating, though not in a negative way because of any flaws or such but because it's an incredibly creative and mentally challenging puzzle game. Probably the best game I've played out of the Jam. Every puzzle managed to offer some unique twist on how the puzzles work.
I do have several problems however. Firstly, the lack of sound. I very happily would have sacrificed a few of the puzzles for some form of sound. As great as it may be to solve a puzzle, I'm sure I would have gotten much more joy with just the simplest of sound effects. Additionally, given the nature of the game you probably could have done something really interesting with the music, have it tune in as you begin to solve the puzzle/
Secondly, the perfect precision that's required on some puzzles is ridiculous.
I cannot see anything being off there (if I remember correctly, it was the size, know for sure it wasn't the speed). All around the loop it looked perfect, and yet it somehow didn't match. A little leniency would have gone a long way into getting that "AHA!" moment rather than "oh, that's surprising" because I was off by less than is visible.
I stopped at around the double wavy dot puzzle to prevent myself from going mad.
Aside from the two above issues this is a great puzzle game. Good luck with scoring highly in the jam.
PS Was this inspired by simian.interface? I ask because it's quite a similar game (though I'd argue that this has more depth to it.)
