Playing on GNU/Linux. I've had some bad luck with Unity Linux builds in /agdg/ jams, where multiple times I needed to play a Windows build with wine for things to work. And so I was happy that everything ran without issue. I like the game's atmosphere. Exploring the wilds with chirping birds is a nice feeling. Some notes
1. It'd be good to know what I have selected after pressing a key. And then after I click, that selection would go away. For example, highlight the sticks in the inventory after selecting them and deselecting them when I place the campfire. This is something you'd surely get to without my commentary, but I thought I'd still mention it.
2. Maybe a camera zoom. The way you move the camera with WASD is interesting. I wasn't expecting it. Glad to see a dev who tries new things. Numpad character movements are also cool. Nice to see a fellow numpad/vi keys dude.
3. In the screenshot that you showed off I don't see problems with the river but in pic below you will see trees growing out of a lake.
4. Getting a Null reference error. No crashes or anything but thought I'd point it out
It probably won't be for everyone (but when should a particular game be for everyone?), but I'm really interested to see where this is going.
