Really awesome game, I love the visual style and the areas are perfect (I really like the courtyard especially, the large scale liminal areas are very nice too). I kept on getting surprised and excited whenever one of the twists happened - especially the very first one and the one with the office (vague so as not to spoil). By the way, is the tunnel from the office area an Ocarina of Time reference?
I did run into a couple of bugs:
1. VSync decreases the look sensitivity (I assume this is just because camera movement is framerate-dependent)
2. At the white house I walked up to the stairs from the left side at a slightly weird angle and as soon as I touched them I couldn't move and had to exit to the main menu and restart.
Neither of these spoilt the experience for me though, I look forward to seeing what else you make in the future!
