Based on feedback, I'd probably add a difficulty option that either makes the antagonist slower or makes it not an instant death, or both. Also maybe more in-game tips about hiding effectively. Oh, and audio options in case the music was too quiet or something. Other than that, I'm very happy with how my submission turned out. :)
Not sure if I'll update it, but might get the itch to knock it out on a weekend day or something, haha. Glad your submission turned out well too!
