This was quite good!
Very PT-esque (which isn't a bad place to start at all IMO), looked great, no bugs that I found, interesting hints at a deep story, and the 'puzzles' were relatively unique! Also, that wooden hallway? Super cool to walk down, really nice touch how it "traps" you into only looking forward.
Made a Lumps Play for it. My let's plays aren't all "OMG SCARY I'M HAVING A REACTION WATCH ME REACT AHHHH"—they're cleanly edited playthroughs with pop-up commentary. Words! Check it out, it's a lot of fun.
You plan on finishing, ya? Please do! I'd love to play a full version. Thanks for being rad, cheers. 🍻
