I applaud your attempt at a story for an 8 hour entry. That takes effort! The game play was pretty straightforwards but functional. I think for your graphics you'd get a lot of mileage out of using a color palette (there's some great websites for generating them, like coolors.co) It really boosts the visuals on games with simple graphics!
I'd really appreciate if you could give my game a shot as well and tell me what you think!
