The art and animations are very nice, the platforming/level design aswell, and the sounds and music leave a good impression, however on the game design side of things the game falls a bit short, the only thing you do is turn on lights, and the snake is a bit wierd, sometimes it seems to just go straight for me and other it just zig zags around, it can come from pretty much any direction and often times its already to late for you to reach a light source. The way the music just cuts abruptly is also off putting.
The game would go a lot better with the theme if the scenery was pitch black and you would carry a torch that would loose range after a certain period of time, there's a another game in the jam which went with that approach, turn on the light. While that game doesn't go much along with the theme either imo, at least gameplay wise I found it more fun.
And if that's not your cup of tea and then some other gameplay element would have made the game more rich and made a big difference.
