Tasso I'm gonna put a list of my responses to your post. Please don't take this as negativity.
1. The game is a FNaF fan-game. All of them are confusing.
2. If you've played FNWaC 1 using a phone/tablet, then you might not be able to play the game due to the large size.
3. If you were to click the lever thing, the door would close/open. If the cow is at your door, just click the lever to keep yourself from getting jumpscared.
4. I used Minecraft images (which were actually images made in "Mine-imator") because I really liked Minecraft and I wanted to do something no one at the time was doing: making a Minecraft and FNaF crossover. The Minecraft images are big. I'll fix these problems with FNWaC 2.
If you have a problem with the game please let me know. I'm doing my best to have FNWaC 1 work on all devices by shortening animations and making the game smaller. If you want to play FNWaC 1 in it's full glory, I suggest getting the .capx file at the official website: http://fivenightswithacow.weebly.com/
