Path of the Oxiflame

Path of the Oxiflame is a 3D sokoban-puzzle-adventure inspired by classic Team Ico games.
It features multiple playable characters as well as numerous puzzle mechanics beyond the classic pushing of boxes.

After a boy and his brother were hunted down by fearsome creatures during an attack on their village, he finds himself in rough shape in an unfamiliar forest. Strange monuments line the path etched with peculiar markings. On a clearing he discovers a brasier, which burns bright with a green flame, that holds a great power...

Aided by the flame, the boy is able to move the massive boulders which can be found all throughout the confines of the forest.
Whoever placed them did it with purpose as if to test someone. But once moved into the correct configuration they reveal the path forward.

The forest is not as peaceful as it appears - those same creatures that attacked the village still lurk in the underwood attracted by the scent of the flame.
The boy can either outrun them or manipulate his surroundings to cut them off or at least buy himself some time.
