Deposited 42 coals into the furness, then a eye apeared untop of the furness. Climed the ladder and it stunlocked me until I typed ESC. Then I picked up another piece of coal, tried to trow it in the fire, was denied agin, and aparently locked out of any interaction, and could not trow away the coal.
Looks promesing, but a lot of bugs in the first 5 min of gameplay
