Haha, it's funny how key elements of a games 'fun' can sometimes be found in things that weren't intended. Some of my favourite games, as well as lots of speedrunning games, are made all the better as a result of them being fun at the core but then also having features that can be mastered by the player in a way that feels like you've 'figured it out'.
Just re-read my comment as I was typing this and want to re-iterate how lovely the lighting was!
