I can see there was more planned than what made it into the version for submission, because I never saw any ammo or health pickups like it states at the beginning. I'm not quite sure where to go it looks like the gates on the sides have numbers but I can't figure out how to open them even after killing tons of spiders. The music  does get a little distracting, and I think you need to add sound effects because right now it feels like there was just a music track slapped over a gameplay video. I also found a bug where you can go out of the bounds at the top of the area but the spiders can't.
