That is all that I have for you, good job reading this far down, comment "wow good thumbnail" if you read this. Or don't. this took too long and its almost 6 am and i have not slept yet and i will not worry about whether or not some stranger online comments and likes this video

This whole video was made because of a bet i made with a friend. If i could make a 30 minute video essay in under 15 days, he would buy me the new talos principle 2 DLC and brother i clutched up. My sleep schedule will never recover but i am 20 virtual dollars richer
