Interesting concept, if I might note just a couple things.
1. The audio can be painfully loud at times and too quiet at other times. There is no shame in aggregating sound effects from across the web, but I would recommend learning a little about audio processing and using something like Audacity to help balance your audio clips across the board.
2. It looks like you have some really interesting lore for your game that you are excited to share! However, I would avoid adding things like an un-skippable text crawl to the beginning of your game, and I would focus more on some of the environmental storytelling aspects. The best way to get other people to care about your lore is to let them experience it as they explore the game!
I don't intend to come off as harsh, I can see the excitement and energy behind this project and that is invaluable. Keep coming back to this, and KEEP publishing. Receiving feedback can be difficult, but it is so important to your growth as a developer. Take the criticism with a grain of salt. Something that I have learned is that people are usually correct about WHAT is wrong with your game, but they aren't always correct as to WHY it is wrong or HOW to fix it.
Anyway, good job. I look forward to seeing this project grow.
