Very, very fun game mechanics. I like how it's this vaguely Spiderman-esque thing, but totally modified for a 2D environment and a fragile object that you need to protect from collisions. Really, I'm very impressed by it. When I first accidentally attached the bulb to the ground and crashed it, I was pleasantly surprised that this was possible in the game, even though it killed me! Added it to my collection to keep trying at it. Also, I really loved the 3D way the game started with the elevator and the warning.
It looks really nice, if a bit overly simple. The audio was mostly fitting, particularly with the sound effects, but it was all a bit quiet, though I guess that fits it for the most part too.
The implementation of the "Lightshow" theme is great, just because the entire game revolves around keeping your light on - not just like you're holding a flashlight or something, but literally making the player the light, as fragile as a lightbulb is. Not sure if you tried to include the "Only One" limitation, but the fragility of the lightbulb did make the one life you have feel more precious than it usually would in a game.
Great concept, and great execution for the jam.
