Just finished the demo. I know the interconnectivity is (one of) the game's major selling point(s), but whenever I realized the solution involved going back to an earlier screen, my reaction was always frustration. I prefer games where everything you need is already on screen and you already know what everything does, but the puzzles are still hard to solve, like Mitoosis (which is free). Would you consider going more in that direction for your next game?
P.S. I'm also not a fan of games that keep introducing new things so part of the puzzle ends up being simply figuring out how to use the new thing(s). I bring this up because the demo does this; I know there's a chance the main game stops introducing stuff after the demo ends, but I've been burned before on this and want to ask that your next game not fall into this unfortunately-all-too-common pitfall.
