This is one of the strongest new game mechanics I've experienced, not even within the Adventure Jam, but in recent memory in general. It instantly spawns ideas in my head about interesting strategies, and the game encourages experimentation without punishing the player for doing so. You've also struck the critical balance of making the puzzles difficult enough to light up the brain cells, without becoming demoralizingly difficult. Bravo. Excellent work.
I also have to say the art style is gorgeous. And kudos for the extra flourish of making the embedded HTML5 version of the game perfectly extend into the itch.io page background. Loved that! The storyline was also very fun, and I enjoyed the ending (I took the 'low road') 😨
I hope you continue with this game further, and flesh out an even bigger version. I would love to see more of the mechanic and world!
I actually recorded my playthrough. If you want to see my impressions as I played, you can see it below (timestamp for your game in the description). Hope that can be useful!
