I like this game. It has a retro Zelda vibe, but with a sorrowful, bittersweet tone.
The light mechanic is interesting, but in practice, I find it more of an inconvenience to have to go back to a statue over and over.
I also didn't realize until near the end that the branches were restoring the light. I thought it was a bug. There should be some communication to the player that they restore light, and maybe a bit of lore.
Speaking of lore, I really liked the story, and would love to know more about what happened and why we're in the situation we're in.
This is a very interesting game, and would love to see it expanded upon. Great job!
