The visuals and sounds are great and the puzzles were fun. I still don't know when dark forest spreads, but I managed to get by. Also, the amount of levels in this demo is a good amount to get an idea of what the game is. Also, just before writing this I played the game for the second time and realized resources are limited. The first time I played a day ago none of the resources I collected were used. I'm not sure how to recreate this as I simply just played it in the browser.
