Honestly it’s not that the puzzles weren’t high quality (they were!). At the beginning I was thoroughly enjoying the concept.
It was just the more I played, the more I noticed how easy it was to cheat mindlessly. Maybe it’s a good thing, it allows players who don’t want to cheat to have the full experience and the people that do to rush through.
I’m glad you went with manual level design over a procedural generator. The pacing of the levels is perfect as it is, but if you’d used a generator it could have been a different experience for everyone, and in such a short development window for a jam, it’s quite possible that some of those experiences wouldn’t have been good.
