I really like the fucking while the player does something else, this game is exactly that. Unfortunately its about 20 minutes long if you meander and even shorter if you solve the puzzles fast.
I am a total bonehead. I have the wrench and the flashlight, the lights are out, and I was able to open the kitchen and the bathroom. also found the books and numbers written in blood. What's next? i can't move the ruby or get the thing out of the bathtub. I also don't know what the numbers are for.
The game has 15 CGs, 3 of which are just idle character sprites. If you want to unpack it, look for Enigma Virtual Box unpacker. I grabbed evbunpack from GitHub and had no problem getting an unpacked version.
