I liked how you can change the controls. I didn't yet know what was awaiting me...
So, you can change controls by providing a different keybind to an action. And game updates the action with new keybind. Only it does not remove the old one. So, if you change your controls quite a bit, it will remember everything you every changed it to, and every button would point to every action and it would result in quite a buggy mess.
The art is good, I quite liked it, but the style didn't fit the game quite well. Given the nature of movement, a winter ice lake would fit it better. Maybe even oiled winter ice lake.
Decisions are quite good, and results are mostly immediately seen. I didn't like that you can't skip the "stories are told, generations are passed" cutscene. Puts it off to try to replay and go for different outcomes. The music and sounds are great.
