Luminesca is a chilled-out underwater exploration game which follows the story of a little creature called Lum. Using the light from your esca you can explore the dark watery depths, uncover ancient machinery, and play with a whole ecosystem of strange creatures. Luminesca is a simple game which intends to create a rich, atmospheric experience.
I think if this game was complete and had 2-5 hours of gameplay that I wouldn't be able to stop until I was finished. It was a nice breath of fresh air from the permadeaths i've become used to (not to say this game won't go that direction eventually).
The ambience reminded me a bit of Aether with the uncanny feeling and loneliness. Also, the subtle story telling (backstory) was great and I hope to learn more of my journey.
I hope that updates continue to happen and that another chapter appears soon.
