I like the core mechanic here! Strong premise for a fun little game. The environment seems pretty well put together, has that horror vibe to it, and mechanically it feels sound. Love the name as well, it perfectly fits the game.
The four things I think would make for an immediate improvement are:
- Speeding up that monster walk animation, so it feels less like the monsters are floating. 2x or 3x would probably help a lot.
- Slightly better signposting of what needs to be done. The first fence doesn't immediately spring out to me as something I can walk through, and trying to find the key can be hard with how small it is. Possibly some lights, arrows, blood trails etc etc would help guide the player.
- 3D audio on the monsters. The sounds are great, but it would be a massive benefit to be able to hear roughly where they are within the level
- Make the death animation more satisfying. Some camera shake, more noise etc. Something to make you go 'damn, I got caught. I'll try again'
For me personally, I got a massive stutter and freeze as I turned the first corner. No idea if that is a universal thing. It's almost certainly just a symptom of it having to load into the browser, but a disclaimer to not panic or close the game while it loads would help keep people playing!
Otherwise, this is a really nice premise. With a few tweaks, it could be a really awesome short experience! Well done everyone involved.
