Incredibly original. It's amazing how such simple gameplay and graphics produce a game of such ambiance. The game was just the right length for what it's trying to do and never overstays its welcome. The puzzles were challenging without being frustrating and, more important, you managed to make a tense atmosphere and, I'd even say, some scary moments with simple 8-bit graphics and with little in the way of jumpscares.
I salute your work, and I hope you keep making gems like this.
