There are a lot of really great features implemented in this game. The stealth mechanic with the fires works well. The crafting works feels like it gives you gradual enough upgrades to not feel too overpowered. It's a little lacking in polish but that's to be expected considering the amount of content you managed to cram into 2 weeks.
My biggest issue was the general lack of contrast. There are ways to make a game feel dark without making it impossible to play without your curtains closed and brightness maxed out. Edit: this was fixed.
Overall though, it was very enjoyable and although it was quite challenging for me, it still felt fair.
