With modifying this file, you are able to skip the intro/seizure warning text and it starts you right at the main menu.

Installpath if installed to C:\ will most likely be here:
C:\Program Files (x86)\Steam\steamapps\common\Teardown
Open this file here with notepad or notepad++, or any text editor of your choice:

<InstallPath>\data\ui\splash.lua

In this file, change these lines (6 and 7) to set the variables to "0":
splashTime = 20
requiredTime = 4

Change it to be:
splashTime = 0
requiredTime = 0

Save the file back to splash.lua, and now the game will start right up into the main menu!
