Really fun game! I have a soft spot for games that let you control the rules of the world itself, and this game definitely delivered on that!
I had a couple thoughts about the new player experience:
1- I didn't see any description of the controls anywhere. That was a bit of a problem, as the "up" button only seems to do anything when you're linked (the first puzzle took me far too long to solve.)
2- The resolution on the Web GL version of the game seems to be a bit too low for the on-screen instructions. (I happened to hit full screen before starting, so it wasn't an issue for me, but I could see players getting a wrong impression from that.)
Overall, though, these were minor things compared to how fun the game was!
