I was shocked at how well the solutions came together. The concept of the game immediately worried me as the type that would fall prey to feeling like you have a correct solution that isn't working because the game wasn't smart enough. This never once happened to me. Every time the game told me something didn't work, it made sense, and every time I reached a good solution it rewarded me. If anything, my only complaint is that it went by a little too quickly. Very few levels actually stumped me, which if anything speaks to how well-made the puzzles were, because it's not like they were overly simple. I do think it should've been much longer, even for the price tag, but what's here is solid.
