Very atmospheric intro and music, but the game doesn't feel much like the intro. Maybe you could replace the tileset and player character with stuff cut from photos?
The game plays well, and is mostly fun. It feels like memorization is the main skill for this game, since the level never changes, and you can't react quickly enough to hazards by the time you see them, so you have to remember what's coming. There's a lot of trial and error.
The sound distorts sometimes. I'm playing in Chrome browser.
