-Simple yet effective and entertaining.
-Great for multiple runs with the utilization of items given at each new start (after you get atleast 1 ending). It could use a save system to faster check some dialogue options (but this might be a feature update).
-Funny dialogues
First run is about 30 minutes to 1 hour depending on how much you want to explore and which ending you will have. After this it's up to you to see everything the game has to offer and it's a lot. It's worth it to make those re-runs.
In my opinion it is not heavy on veganism/vegetarianism/etc "propaganda" as some will say. It does make you think on your choices though and what changes should be made in the food industry.
Overall it is a fun game for everyone as long as you are not very sensitive an animal abuse issues (some are hinted, some are shown and they can be avoided all together based on your choices [especially after a change in an in game video]).
Exploration is recommended to get a full picture of the world.
Improvements could be made on a save system, smoother walking (sometimes your character will turn for so reason or seem stuck somewhere - but he is not, while looking at his back try to move back) and some additional options.
A future update could bring new things to the game as, since it's developed by a small team, it has missed some opportunities for extra branches.
You'll run into the occasional visual bug but nothing that will break your game.
