Wow! Thank you so much for all the kind comments. I finished playing The Witness recently and some of its puzzle design philosophy rubbed off on me (I definitely ripped my hair out and a few pages on my notebook playing that game). I won't be working more on this game anytime soon as I have other work commitments, but I'm hoping that some other aspiring game developer in the future will enjoy playing this short game and get inspired to make a longer, more polished puzzle game similar to this. :)
