This was a pretty pleasant puzzle game! I think the art is charming and the UI fits very well, and vibes in total work for the cozy Autumn feel you're going for. It's got some pretty tricky puzzles, but the star system helps balance difficulty by allowing players to get more or less ambitious, which helps with how open the system is. It almost feels like a puzzle game by way of tactical RPG, where controlling your character's movement is the big factor to winning.
It didn't run great in my browser, with some occasional lag spikes and choppy audio, but my computer isn't great so this doesn't mean it's gonna chug on all devices.
More importantly, this is a really difficult problem to address, but from a marketing perspective I think this game's appearance and title could be misleading enough to detract players who may otherwise enjoy it, or vice versa. The title "Forest Farming" combined with an isometric grid view immediately evokes imagery of a farming sim a-la Farmville or Harvest Moon, which the game most certainly is not. I could envision advent puzzle game fans passing this one by simply out of the game looking like a genre it isn't, which would be a shame since I'm certain fans of these types of puzzle games would really enjoy this!
Unfortunately, it's hard to come to a solid "fix" to that problem short of changing the name or aesthetics, but I definitely think it's something worth keeping in mind since "perceived genre" is a huge part of game marketing. Of course, if that isn't important to you I fully respect that, in which case I think the actual content of the game works fine!
In terms of puzzles, I think one aspect I would like to see is a way to tell easily which house belongs to which hedgehog, and how many steps "non-player" entities such as humans have, to make it easier to strategize without resetting. It'd be a minor quality of life improvement, but one that I think would help make the puzzles more "fair".
Overall though, this is very good at capturing the cozy and cute vibes it's trying to! The accessible nature of the star rankings helps improve the game's overall reach without dumbing down the difficulty, and it's pretty solid all around! Very nice work here!
