Crawling to forget the nothingness

One day you wake up as a large bug. Other than that, everything is as gray and monotonous as it used to be. Crawl around the building to discover its secrets, or just crawl around your own room. Spew acid to defend yourself against attacks from other insects, but be careful as attacking reduces your health. Once it gets darker, you can return to your room and go sleeping. Each day something changes.
