Nice game, like it!
Story: 10/10; didn't expect to see it there
Visuals: 9/10; postprocessing and effect are well done, but I think sprites need to be improved
Implementation: 8/10; everything works fine, but sometimes game doesn't feel very polished
Gameplay: 8/10; interesting mechanics, but nothing new
Overall: 9/10
This game is really good and better than 90 percent of all games on the jam. Hope you liked the feedback, you can ask me whather you want, if you need more feedback on specific topic.
