The art is great. And mechinics is interesting, seems like it could become a big project, hope you continue to develop it. The hint made my life too easy, I found the eye quickly after looking at it)
I found an interesting issue: the game allows you to crawl by pressing ctrl+wasd, but when you press ctrl+w browser tab closes (I use chrome and it's a hotkey here) and you need to restore the tab and start the game from the beginning. Probably you do not need the crawling mechanics at all? Or you can use some other key for it.
Overall, really cool game, good job!
