Maybe like, remove the 'horrible' from the title because, apart from the fact that it almost melted my gpu, this is genius. Now I don't work with 3D games but whatever rendering magic you've done, please do more. Really amazing and interesting concept. Although unfortunately I don't see how it fits the theme. Some more work in audio would've made it really interesting, specially using stereo audio to further distort the sense of space. 

Extremely cool idea regardless, make further updates to this if possible, slightly improve the orientation of the top down view, and you have your next Benett Foddy game
