The engine could use some improvements. It lags. It sometimes takes too many extra clicks to perform a simple action (pop up bag, take the item I just picked up, click object to use with...) The click areas are very small and the cursor changes randomly from arrow to hand and back.
In the game itself, cannot light up two pieces of wood, only three? At least a text should be popped up when trying to light it saying too few wood. No need for clues where preconditions are realistic and natural.
Otherwise the puzzle was fine, graphics also OK and made an entertaining game.
