Not a bug that I encountered. Possibly something to do with it using Vulkan as the graphics API?
I have the same problem, if you need some info/specs from me, let me know
I found that medium settings makes it look normal though I can't test myself as I'm on Linux. I'm interested to know your specs
Yep that works! Just played the first 2 levels (though I did get caught and then nothing seemed to happen but restarted)
Specs: i5-4690K, GTX 980, Windows 10. Running latest stable graphics drivers.
