The game looks very nice and i like the art style. Sadly there was no tutorial or keybindings. So I had to figure it out myself.
WASD - Walking
Mouse - Looking
CTRL - Make cursor free and allow for interactions
After getting to the cauldron i was stuck, i got a flower and went to the tree house. I couldn't really figure out how to give the flower to the tree house to open its door. Maybe i missed something, if so i can give it another try.
So sadly all doors stayed closed for me :(
