The game is great, really unique and spooky. I love the fact you cannot stay in one spot for too long otherwise the spider will spawn, therefore you need to constantly move, that's a really cool idea. Also, fireflies don't need to be visible for you to collect them, which makes perfect sense since they are small, I love that. Maybe you could add some kind of waves of enemies, currently it's kind of easy. Keep up the good work! :D
