This was a super refreshing take on the 'no lights' idea. I love that the lack of lighting didn't become 'feel your way round the dark', but instead, the light was actually an element of the puzzle. Many other games like this create difficulty with the darkness limiting what you can see, but this focussed more on the properties of lit things. I found it super cool that rotating lights and moving green lights worked, that must've taken a lot of painful programming to implement. I'm actually surprised that you didn't use them more, considering the interesting problems you could've made with them. So yeah, great game, I managed to finish it, but it was a bit tedious at times.
