This is gorgeous! Somehow, I didn't realise how much I wanted a game that so strongly emphasised falling/drifting through 3D voids, so maybe you know me better than I do. The textures are lovely, and the way they tiled reminded me of wrapping paper, so you get bonus points for seasonal appropriateness. The walk to that doorway was a little excruciating, partly because I accidentally reset midway through my first attempt thinking that it might reset the camera perspective rather than the game itself, and also because I only realised you could get there via the blue thing on my third playthough.

If you made a downloadable version I would indeed download it, but only do it if you want to.

Oh and just to check, the fade to white is the end, right?

I like this very much. It looks terrific on my screen. Playing in my bed with the screen on my chest gives me two very contradictory feelings : nausea and internal peace at the same time. I tried to play with various background music.
the sensation of falling is scary and enjoyable at the same time. It reminds me of dreams I have

One more vote for a downloadable version.
This is a beautiful game. The drawn textures work so well in this form.

Not being able to look up or down or strafe makes me less conscious of the rooms as 3D spaces. That, together with the flat textures and lack of lighting, makes me very aware that my screen is a 2D, pictorial plane. Playing the game feels more like looking at a painting move and shift before me than exploring a space.
