Hah, I'd love to show you but it's broken, I was messing around trying to get dynamic lighting working and gave up. I'm not even sure I'd link it here if it did work because it was done with Pico-8. Mine was top-down though and you had a radius of light around you most of the time, so outside of making the player's surroundings dark our two ideas were fundamentally pretty different.
Whenever I get the chance I'll probably remake it again in Cocos Creator, just to see if it would actually be any fun to play. If I do I'll definitely post it here.
