Hello everyone and sorry for the lack of updates. A few things happened that slowed down the development, but it's not stopping.
I switched the game to Unreal Engine 5, and that will improve the lighting a lot, among other things. I've also been working on increasing the brightness of the environment and overall lighting, to make it easier to see. I am also adding a settings menu, so you can change some game options including the brightness.
And I also am making a couple of changes to one of the puzzles in the demo.
I'll upload an updated demo soon!
