Everything was fine, until the asteroids appeared... Instructions are in-game! Current known glitches: sometimes an asteroid goes on a rampage and charges through destroying all windows in its path. watch out for these.
a person in existence created a paper game called "it's a asteroid!" where you draw a person in a house and draw lines on a lined piece of paper toward the house, you put pressure on the paper so that eventually the pencil/pen would rip to create an "explosion", when it hits the person it's game over - or so i think. it's been a while. another detail i remembered from the paper game is that when the asteroids hit the mountain under the house, it sorta drills through and bores its way upwards toward the house credit to @meepisthesheepis
