So, this is actually really really damn cool. Using the classical look of the Flatwoods monster, putting you in a constantly warping house... all the ideas are great, and it all LOOKS awesome.
However, to be brutally honest, the gameplay just ended up being flat out frustrating more than anything. Enemies constantly sneak up on you from the back, and you are basically just running around headlessly hoping you are lucky enough to have a Shambler trap, since those guys especially get annoying.
My victory at the end was little more than pure luck of running into enough Material to enter the portal once I stumbled across it. it didn't feel like a fight. It felt like a fluke.
But with that said, if that was ironed out, this could be an AMAZING randomized horror experience! So please, it would be awesome to see you work more on this. Flatwoods could easily be great!
