After Light Fades

Here is an excerpt from After Light Fades's Steam description:

Venture out into an epic odyssey with 7 artefacts your lost love Aura left behind. As you puzzle through the worlds, you bring each artefact to an abyss an cast it in, letting go and allowing yourself to unfold into a freer and lighter person, one step closer to becoming free of heartache, and transforming yourself into something greater.

After Light Fades is a sokoban with a rich and magical plethora of elements for you to get creative with! Everything from magic mirrors, clones, teleports, angels, transmutation crystals, nature elementals, electrical circuits, magnets, fire propagation, growing vines, and so much more!

The uniqueness of the puzzle solving comes not in the typical hero-to-object relationship, but in the relationships objects have with each other - an angel be used to tow a crystal, a crystal can transmute earth into energy, an angel pushed into a seed will grow a vine. These puzzle mechanics are all rich metaphors for Alice's journey of heartache, letting go, and ultimately transforming herself into the higher form of a nature alchemist.

Alice embarks on her journey after her partner Aura's tragic death in a house fire. Sifting through the ashes, she finds seven ordinary-looking objects, seemingly unharmed by the fire. Compelled by mysterious emotions tied to these items, she resolves to visit seven significant places they'd shared, casting each artefact into an abyss, to let go and find solace.
