I really wanted to like this one. Shades of Haunted House and all.. But after about ten minutes of wandering in two sessions, really couldn’t tell what to do. I’m actually not sure both times whether it crashed or I died. The screen went black and unresponsive, and nothing showed in the console.
One low-hanging fruit: You ought to put some texture on the wall edges, or have a moving floor pattern. As is, there’s a lot of times when you can’t tell whether you’re actually moving or not.
