Wow. At the risk of sounding pretentious there's an eerie beauty to this. Your art style is really something - simple shapes and objects and let the lighting do a lot of the work.
One thing that would make it even better is a bit of an indication of the failure condition. Sometimes I would slingshot a suuuuuuuper long way and be fine, sometimes I would get zapped back when my star was barely off the screen but going in the same direction.
I get it though, everyone here does, it's super hard to make a game in 3 days, especially one this unique and well presented. I hope you'll take the concept further post-jam because you have something here.
