Hey, just d/l and played your game, still going actually, my crit is that at first I had no idea what I was doing. It wasn't until I did a medium level puzzle that I started to understand how to play the game, the first three puzzles I did didn't teach me how to play, I just put random things in and it worked. I didn't feel it was complex enough to register what was going on.
Just my two cents....
anyway now that I get it I'm really digging the game. Also, the music is awesome, nice ambiance.
edit: just played the 5th bronze puzzle, from the left, and that was a good easy one. I think I would've understood what was going on there, but idk
Really valuable observation! I've been struggling with how to present the puzzles. Earlier, I was told they were too hard, but I have now seen a couple people do the random thing and not learn anything from the ones that are too easy. (Originally the first silver one was my "easiest".)
Making the puzzles is tricky. I do have a utility that allows me to test to verify the solution, and shows if there are multiple solutions--a couple of the easy ones are that way.
This is the biggest challenge of this puzzle game: communicating how the puzzle works.
I take it the sound is not breaking up. That would be good. It might also be possible if things got too busy for the volume to get too loud, which makes a nasty noise, rather than a hiccup.
